INTRODUCTION:

Sesbania grandiflora, also known as "Vegetable Hummingbird" or "Agati," is a plant species renowned for its wide range of medicinal properties. It belongs to the legume family (Fabaceae) and is native to tropical and subtropical areas, including Southeast Asia, Africa, and India. For centuries, the plant has been utilized in various traditional medicine systems, not only for its nutritional value but also for its ability to treat numerous health conditions.¹

The plant's leaves, flowers, and seeds are all edible and contain several bioactive compounds that offer multiple health benefits. Recently, there has been growing interest in its potential to treat migraines, especially for those seeking alternative therapies to conventional migraine medications Migraine is a widespread neurological condition that affects millions of people globally.² It is characterized by recurring, intense headaches, often accompanied by symptoms such as nausea, vomiting, and increased sensitivity to light and sound. These episodes can last from hours to days, severely impacting the quality of life. The exact causes of migraines are not fully understood, but it is believed that a combination of genetic, environmental, and neurovascular factors contributes to the condition.³ Changes in brainstem activity, neurotransmitter imbalances, and abnormal brain activity are thought to be involved, particularly in the dilation and constriction of blood vessels in the brain.⁴ Traditionally, migraine treatment has involved a combination of pharmaceutical drugs, including abortive treatments such as triptans and analgesics to relieve symptoms during an attack, and preventive treatments like beta-blockers, anticonvulsants, or antidepressants to reduce the frequency and severity of migraines.⁵ While these medications are effective for many people, they do not work for everyone and may cause side effects ranging from mild to severe. This has led some individuals to explore natural remedies, including herbal treatments, as alternatives. Among these, Sesbania grandiflora has emerged as a promising candidate for providing migraine relief.⁶ In traditional medicine, Sesbania grandiflora has been used to treat various ailments, such as headaches, fever, inflammation, digestive issues, and skin problems. The plant's medicinal effects are attributed to the bioactive compounds found in its leaves, flowers, and seeds, which include flavonoids, alkaloids, saponins, and tannins. These compounds are believed to provide anti-inflammatory, analgesic (pain-relieving), and neuroprotective benefits, potentially making Sesbania grandiflora an effective natural remedy for migraines.⁷

One of the main ways in which Sesbania grandiflora may help alleviate migraines is through its anti-inflammatory properties. Inflammation is considered a key factor in the development of migraines. During an attack, inflammatory mediators such as prostaglandins and histamines are released, leading to the dilation of blood vessels in the brain and resulting in pain.⁸ Sesbania grandiflora, particularly its leaves and flowers, contains flavonoids that have been shown to reduce the production of these inflammatory compounds, which may help lessen the severity of migraine pain.⁹

Additionally, these anti-inflammatory effects may contribute to reducing the frequency of migraine attacks, making Sesbania grandiflora a viable option for preventing migraines. Another important aspect of migraine treatment involves managing blood flow in the brain. During a migraine, blood vessels in the brain constrict and then dilate, leading to pain. Some compounds found in Sesbania grandiflora, such as saponins, are believed to help regulate the tone of blood vessels and promote vasodilation (the widening of blood vessels).¹⁰ This vasodilatory effect may help prevent the constriction of blood vessels during the onset of a migraine and relieve the associated pain. Additionally, saponins have been shown to have neuroprotective properties, which may further reduce neurological symptoms commonly seen in migraines, such as visual disturbances and sensory auras. Moreover, the analgesic properties of Sesbania grandiflora may help alleviate the pain associated with migraines.¹¹ Traditional uses of the plant involve preparing herbal infusions, poultices, or extracts to relieve headaches. These preparations are thought to target pain pathways in the nervous system. Alkaloids, another key group of bioactive compounds in Sesbania grandiflora, are known to interact with pain receptors in the brain and central nervous system, potentially reducing pain perception and providing relief from migraine discomfort. The combined anti-inflammatory, analgesic, and neuroprotective effects of these compounds make Sesbania grandiflora an attractive natural alternative for those looking to manage their migraines without relying on synthetic medications.¹² While traditional uses of Sesbania grandiflora to treat headaches and migraines are well-established, modern scientific research into its effectiveness and safety for migraine treatment is still in its early stages. Preliminary studies and anecdotal evidence suggest that extracts of the plant may offer promising results in alleviating migraine symptoms.¹³

However, more extensive clinical trials involving larger sample sizes and more rigorous methodologies are required to confirm its effectiveness, identify the optimal dosage, determine the best mode of administration, and evaluate its long-term safety profile. A number of animal and laboratory studies have begun to explore the pharmacological effects of Sesbania grandiflora and its potential role in treating migraines.¹⁴ These studies have focused on isolating and characterizing the specific bioactive compounds in the plant, as well as testing their effects on migraine-like conditions in animal models. While some of these studies have yielded promising results, further human clinical trials are necessary to gather stronger evidence supporting its use as a migraine treatment. As the demand for natural alternatives to conventional migraine treatments continues to rise, Sesbania grandiflora may represent a valuable addition to the growing field of botanical therapies for this debilitating condition. Its potential to offer a safer, more accessible option for those suffering from migraines makes it a compelling subject of interest for future research in the area of phytomedicine.¹⁵

Botanical Profile of Sesbania Grandiflora:

Sesbania grandiflora is a rapidly growing, deciduous tree or shrub commonly found across tropical and subtropical regions of the world. Belonging to the Fabaceae family, it is known by various names, such as "Agati," "Vegetable Hummingbird," and "Katurai," depending on the region.¹⁶ This plant is particularly prevalent in Southeast Asia, India, and parts of Africa. Renowned for its culinary uses, its leaves, flowers, and pods are edible, while also being celebrated for its medicinal qualities, which have been recognized in traditional medicine for centuries. Sesbania grandiflora typically reaches a height of 5 to 10 meters, with a slender, upright trunk. The leaves are large, pinnate, with many leaflets, giving the plant a distinctive lush green appearance.¹⁷ The tree produces large, striking flowers that are usually white, pink, or purple and have a unique shape resembling a hummingbird in flight, which attracts pollinators hence its nickname "Vegetable Hummingbird." The plant also produces long, cylindrical pods containing seeds, which are used in some regions for medicinal purposes.¹⁸ In traditional medicine, various parts of Sesbania grandiflora, including its flowers, leaves, seeds, and roots, have been employed to treat numerous ailments such as fever, digestive issues, inflammation, and skin conditions. It has also been used to alleviate headaches and migraines in various cultures, and modern research is increasingly recognizing it as a potential natural remedy for migraine relief.¹⁹

Phytochemical Composition of Sesbania Grandiflora:

The medicinal effects of Sesbania grandiflora can be attributed to its abundant phytochemical composition. The plant contains a variety of bioactive compounds, such as flavonoids, alkaloids, saponins, tannins, and phenolic compounds, each contributing to its therapeutic properties. These compounds work together to provide anti-inflammatory, analgesic, and neuroprotective benefits, making them vital in the management of migraines.²⁰

Flavonoids:

Flavonoids are the most prevalent bioactive compounds found in Sesbania grandiflora. These polyphenolic compounds are known for their antioxidant, anti-inflammatory, and neuroprotective properties. The primary flavonoids in the plant include quercetin, kaempferol, and isorhamnetin, all of which help reduce inflammation by inhibiting the activity of cyclooxygenase (COX) enzymes involved in producing inflammatory mediators like prostaglandins. Additionally, flavonoids help stabilize blood vessels and reduce their permeability, which is beneficial in treating migraines. During a migraine, the excessive dilation of blood vessels in the brain causes pain and inflammation. Flavonoids may reduce this vascular reaction, leading to less severe migraine attacks.²¹

Alkaloids:

Alkaloids are nitrogen-containing compounds found in Sesbania grandiflora, especially in its leaves and seeds. Notable alkaloids include sesbanine and sesbanamine, which are known for their analgesic and antispasmodic properties. These compounds can interact with specific receptors in the central nervous system to reduce pain signaling, which is essential for migraine management. Alkaloids may also have a vasodilatory effect, helping alleviate the vascular constriction that occurs during migraines. By acting on blood vessel smooth muscle, alkaloids help prevent vasoconstriction and the subsequent pain that typically accompanies migraines.²²

Saponins:

Saponins are another significant group of bioactive compounds found in Sesbania grandiflora, especially in the leaves and flowers. Known for their anti-inflammatory and immunomodulatory properties, saponins work by reducing the production of inflammatory cytokines and mediators, including prostaglandins and histamines, which contribute to the onset of migraines. Furthermore, saponins promote vasodilation, or the expansion of blood vessels, which helps prevent the constriction that often occurs during migraine attacks. These compounds also have neuroprotective effects, shielding the brain from oxidative stress and neural damage that can result from chronic migraines.²³

Tannins:

Tannins are polyphenolic compounds with astringent properties present in the leaves, seeds, and flowers of Sesbania grandiflora. These compounds possess both antioxidant and anti-inflammatory effects, reducing oxidative stress and inflammation. Tannins have been shown to inhibit enzymes involved in inflammation, alleviating migraine pain. Their antioxidant properties are particularly important because oxidative stress is a key factor in triggering or worsening migraines. By neutralizing free radicals, tannins help protect brain cells from oxidative damage, which is vital for neuroprotection during migraine episodes.²⁴

Phenolic Compounds:

Phenolic compounds, such as phenolic acids, are found in various parts of Sesbania grandiflora. These potent antioxidants help neutralize free radicals, reducing oxidative damage to cells and tissues. The neuroprotective and anti-inflammatory properties of phenolic compounds are significant in migraine treatment, as oxidative stress and inflammation are major contributors to migraine pathophysiology.²⁵

MIGRAINE:

A migraine is a type of headache characterized by intense, throbbing pain, often on one side of the head. It is typically accompanied by other symptoms such as nausea, vomiting, and heightened sensitivity to light (photophobia) and sound (phonophobia). Migraines can last for hours or even days and can be severe enough to interfere with daily activities. The exact cause of migraines isn't fully understood, but they are believed to be the result of a combination of genetic, environmental, and neurological factors. Some common triggers for migraines include stress, hormonal changes (such as those related to menstruation), certain foods, lack of sleep, and bright lights or strong smells.⁴¹ There are typically four stages of a migraine attack:

1. Prodrome: This is the early warning phase, where some people experience symptoms like mood changes, neck stiffness, or food cravings.

2. Aura: Some individuals experience visual disturbances (like flashing lights or blind spots) or other sensory disturbances, often right before the headache begins.

3. Headache: This is the main phase, marked by throbbing or pulsing pain, usually on one side of the head.

4. Postdrome: After the headache subsides, individuals may feel drained or fatigued, sometimes referred to as a "migraine hangover." Migraines are thought to involve changes in brain activity, specifically related to nerve pathways, neurotransmitters (like serotonin), and the blood vessels in the brain.⁴²

Pathophysiological of Migraine:

Migraine is a complex neurological condition marked by recurrent, intense headaches, often accompanied by symptoms such as nausea, vomiting, and heightened sensitivity to light (photophobia) and sound (phonophobia). While the exact mechanisms behind migraines are not fully understood, they are believed to involve a mix of genetic, environmental, and neurovascular factors. The processes behind a migraine attack can be broadly categorized into neural activation, vascular changes, inflammatory responses, and neurotransmitter imbalances.⁴³

Genetic and Environmental Factors:

Genetic Predisposition: Migraines tend to run in families, suggesting a genetic link. Certain gene mutations, especially those related to ion channels or neurotransmitter systems (e.g., serotonin receptors), can increase susceptibility to migraines. A rare form of migraine, called familial hemiplegic migraine (FHM), is associated with specific genetic mutations. Environmental Triggers: Migraines can be triggered by factors like stress, hormonal shifts (e.g., menstruation), sleep disturbances, certain foods, bright lights, or strong odors. These triggers can activate or worsen the underlying pathophysiological mechanisms.⁴⁴

Cortical Spreading Depression (CSD):

Cortical spreading depression (CSD) plays a critical role in the development of migraines. It involves a wave of depolarization spreading across the cortical neurons, followed by a period of neural suppression. Initiation: CSD typically begins in the occipital cortex (responsible for vision) and spreads to other areas, including sensory and motor regions. This wave of electrical activity leads to increased metabolic demand and disrupts normal neural function. Symptoms: The depolarization is followed by neuronal inhibition, which may lead to visual disturbances like flashing lights or blind spots (aura). This spreading also activates pain pathways and inflammatory processes in the brain, contributing to headache development.⁴⁵

Activation of the Trigeminovascular System:

The trigeminovascular system plays a central role in migraine pain. It involves the trigeminal nerve, which innervates parts of the face and head, and the cranial blood vessels. Activation of this system leads to the release of inflammatory substances and pain. Trigeminal Nerve Activation: During a migraine, the trigeminal nerve becomes sensitized, releasing neuropeptides like calcitonin gene-related peptide (CGRP), substance P, and neurokinin A. These compounds cause blood vessels to dilate, increase the permeability of the blood-brain barrier, and trigger an inflammatory response in the brain. Neurogenic Inflammation: Activation of the trigeminal nerve leads to inflammation in the meningeal blood vessels (vessels around the brain), which causes pain and makes pain pathways in the brainstem more sensitive.⁴⁶

Vascular Changes:

Initially, vasoconstriction (narrowing of blood vessels) in the brain may occur, contributing to the aura phase of the migraine, which typically lasts 20–30 minutes and is characterized by visual disturbances. This phase is thought to result from reduced blood flow to specific brain areas, particularly the visual cortex. After the aura phase, vasodilation (widening of blood vessels) occurs, especially in the meningeal vessels. This increases blood flow and is associated with the headache phase. The expansion of blood vessels stretches surrounding pain-sensitive tissues, resulting in headache pain. However, recent research challenges the vascular hypothesis, suggesting that neural mechanisms may play a more significant role in initiating migraines than vascular changes alone.⁴⁷

Neurotransmitter Imbalance: Serotonin (5-HT):

Serotonin is a key neurotransmitter in migraines. Fluctuations in serotonin levels during a migraine may contribute to both the onset and progression of headaches. Low serotonin levels are thought to be involved in triggering migraines, while dysfunction of serotonin systems may affect pain sensitivity. 5-HT1 Receptors: These receptors are involved in constricting cranial blood vessels. Dysfunction in these receptors may contribute to the vasodilation seen in later stages of a migraine. CGRP (Calcitonin Gene-Related Peptide): CGRP is a neuropeptide crucial for vasodilation and neurogenic inflammation during a migraine. Elevated levels of CGRP are detected during an attack, and treatments targeting CGRP or its receptors have been developed for migraine relief. Dopamine: Dopamine, another neurotransmitter, plays a role in the nausea and vomiting associated with migraines. It may contribute to the discomfort many individuals experience during attacks.⁴⁸

Central Sensitization:

In chronic migraine sufferers, a process called central sensitization occurs, where the central nervous system becomes more sensitive to pain. Regions of the brainstem and spinal cord involved in pain processing become overly responsive, leading to heightened pain perception. Central sensitization is believed to cause allodynia (pain from non-painful stimuli) and increased sensitivity to light, sound, and touch, common symptoms experienced during a migraine.⁴⁹

Hormonal Influence:

Hormonal fluctuations, particularly related to estrogen, significantly impact migraine development. Migraines are known to worsen or occur around menstruation, pregnancy, and menopause. A drop in estrogen levels before menstruation may trigger migraines in some women. Estrogen and progesterone influence serotonin, which regulates pain and vascular tone during migraines.⁵⁰

Role of the Brainstem and Hypothalamus:

The brainstem, particularly the trigeminal nerve nuclei, is central to processing migraine pain. It regulates autonomic symptoms of migraines, such as nausea and vomiting, and mediates the sensitivity of the trigeminal nerve. The hypothalamus, which controls the sleep-wake cycle and various autonomic functions, also plays a role in migraines. Changes in the hypothalamus may influence the timing and severity of migraines and contribute to symptoms like fatigue and food cravings.⁵¹

Mechanisms of Action:

Sesbania grandiflora, commonly known as the Hummingbird Tree or Agati, is traditionally used in various forms of folk medicine, although scientific research on its effectiveness in treating migraines is still in progress. Despite the lack of extensive clinical studies specifically focusing on its effects on migraines, its known pharmacological properties allow us to speculate on how it might help alleviate migraine symptoms.⁹

Anti-inflammatory Mechanism:

Migraine Pathophysiology: During a migraine, the activation of the trigeminovascular system triggers the release of inflammatory neuropeptides like CGRP, substance P, and neurokinin A, causing vasodilation, peripheral sensitization, and inflammation of the meningeal vessels. These processes significantly contribute to the pain and other symptoms of migraines. Sesbania grandiflora's Action: The plant contains bioactive compounds such as flavonoids and phenolic acids, which have known anti-inflammatory properties. These compounds may inhibit the release of inflammatory mediators like CGRP and substance P, thereby reducing trigeminal nerve activation and inflammation. This could help decrease neurogenic inflammation in the brain, a key factor in migraine pathophysiology. By mitigating inflammation in the meningeal vessels and surrounding neural tissue, Sesbania grandiflora may relieve pain and prevent the intensity of a migraine attack.⁵²

Analgesic (Pain-Relieving) Effects:

Migraine Pathophysiology: Migraines are characterized by severe, throbbing headaches associated with vascular changes, inflammation, and neural activation. Pain relief in migraine treatments often involves inhibiting pain pathways, including those mediated by prostaglandins and neurotransmitters. Sesbania grandiflora's Action: Sesbania grandiflora has been traditionally recognized for its analgesic effects, likely due to the inhibition of pain receptors and reduced inflammation. The active compounds may work similarly to non-steroidal anti-inflammatory drugs (NSAIDs) by blocking cyclooxygenase (COX) enzymes, thereby preventing the production of prostaglandins, which are involved in pain and inflammation. By reducing COX enzyme activity, Sesbania grandiflora may help alleviate migraine-related pain. Additional Mechanism: The plant may also influence serotonergic pathways, as serotonin plays a crucial role in pain modulation during a migraine. Many migraine treatments target serotonin receptors to relieve pain and manage attack onset. By stabilizing serotonin levels or enhancing serotonin receptor activity, Sesbania grandiflora might help reduce the severity and frequency of migraines.⁵³

Vasodilation and Vasoconstriction Regulation:

Migraine Pathophysiology: A primary characteristic of migraines is vascular dysfunction, which involves vasoconstriction (narrowing of blood vessels) during the early phase, often linked to the aura, and vasodilation (expansion of blood vessels) in the later phase, which is associated with the headache. Abnormal changes in blood vessel diameter contribute to migraine pain and.

Discomfort. Sesbania Grandiflora's Action:

While the vascular theory of migraines has been debated, it remains an essential part of migraine pathophysiology. Sesbania grandiflora has shown vasodilatory effects, likely due to compounds such as flavonoids and saponins. These compounds may help regulate blood vessel tone by promoting vasodilation and reducing the constriction that occurs during a migraine. Balanced Vascular Function: By stabilizing vascular tone and preventing excessive vasoconstriction or vasodilation, Sesbania grandiflora may reduce abnormal blood flow changes that trigger migraine pain. The plant may also promote smooth circulation in cerebral blood vessels, improving overall vascular health and reducing vulnerability to the vascular changes seen during migraines.⁵⁴

Neuroprotective Effects: Migraine Pathophysiology:

Migraines are associated with cortical spreading depression (CSD), a wave of neuronal depolarization followed by a period of neural suppression. This phenomenon is believed to cause the aura phase and contributes to the headache phase of a migraine. Disruption of normal brain function during CSD intensifies the migraine experience. Sesbania grandiflora's Action: Sesbania grandiflora contains bioactive compounds such as alkaloids and flavonoids, which are thought to have neuroprotective properties. These compounds may help protect neurons from excitotoxicity and damage during CSD, reducing the risk of neuronal injury. Reduction of Neuronal Sensitivity: The neuroprotective effects of Sesbania grandiflora may involve stabilizing ion channels in neuronal membranes, preventing excessive depolarization and reducing neuronal hyperactivity during CSD. By decreasing neuronal excitability, the plant may help prevent the onset of migraines or inhibit the progression of an ongoing attack.⁵⁵

Serotonergic Modulation: Migraine Pathophysiology:

One well-known feature of migraines is the fluctuation of serotonin (5-HT) levels in the brain. The depletion of serotonin is thought to contribute to the onset of migraines. Sesbania grandiflora's Action: Sesbania grandiflora contains compounds that may interact with serotonin receptors, potentially helping to stabilize serotonin levels in the brain. Some evidence suggests that flavonoids and other bioactive compounds in plants like Sesbania grandiflora can modulate serotonin release or influence serotonin receptors (particularly the 5-HT1 receptor), which is important in regulating vasoconstriction and vasodilation in the brain. Regulation of Serotonin Levels: By regulating serotonin levels, Sesbania grandiflora could reduce the susceptibility to serotonin fluctuations that often trigger migraines, particularly in individuals sensitive to serotonin depletion.⁴⁰

Antioxidant Properties: Migraine Pathophysiology:

Oxidative stress, where free radicals outnumber the body's antioxidants, has been implicated in migraine development. Increased oxidative stress in the brain can cause neuronal damage and trigger migraines, especially in genetically predisposed individuals. Sesbania grandiflora's Action: Sesbania grandiflora contains antioxidants, such as flavonoids, phenolic acids, and vitamin C, which help neutralize free radicals and reduce oxidative stress. By protecting neuronal tissues from oxidative damage, the plant may help prevent or lessen the severity of migraines, particularly those triggered by oxidative stress.⁵⁶

Modulation of Trigeminovascular System:

Migraine Mechanism: The trigeminovascular system, involving the trigeminal nerve and cranial blood vessels, plays a crucial role in migraine pain initiation. Activation of this system leads to the release of neuropeptides like CGRP, which causes vasodilation and contributes to migraine pain. Sesbania grandiflora's Action: The anti-inflammatory and analgesic effects of Sesbania grandiflora may help modulate trigeminal nerve activity, reducing excessive release of CGRP and other pain-mediating substances. This could prevent the cascade of events that leads to the headache phase of a migraine.⁵⁷

Hormonal Modulation (Estrogen Regulation):

Migraine Pathophysiology: Hormonal fluctuations, especially those involving estrogen, are significant triggers for migraines, particularly in women. Migraines often worsen around menstruation, pregnancy, and menopause, periods marked by substantial hormonal changes. Sesbania grandiflora's Action: Though not fully researched, some plant-based compounds are known to have estrogenic effects, meaning they can interact with estrogen receptors in the body. If Sesbania grandiflora contains estrogen-like compounds, it may help balance estrogen levels and reduce hormone-driven migraine triggers.⁵⁸

CONCLUSION:

Sesbania grandiflora, also known as the Hummingbird Tree, exhibits a range of pharmacological properties that suggest it could be beneficial in the management of migraines. Although scientific investigations specifically targeting its effectiveness for migraines are limited, the plant’s known anti-inflammatory, pain-relieving, neuroprotective, and antioxidant qualities point to its potential in alleviating migraine symptoms. The active compounds found in Sesbania grandiflora, including flavonoids, alkaloids, and saponins, may influence crucial mechanisms involved in migraine development, such as reducing inflammation, regulating blood vessel function, and balancing serotonin levels. Moreover, its ability to modulate the trigeminovascular system and offer neuroprotective effects against cortical spreading depression strengthens its potential role in reducing migraine pain and preventing the progression of an attack. Despite these promising properties, additional clinical research and trials are needed to confirm the therapeutic efficacy of Sesbania grandiflora in migraine treatment. More in-depth studies will be required to assess its safety, determine the appropriate dosage, and understand its long-term effects. As research progresses, Sesbania grandiflora could become a valuable natural treatment for migraines, offering an alternative or complementary option alongside traditional migraine management therapies.

RESULT:

Although limited clinical studies specifically focus on Sesbania grandiflora for migraine treatment, existing evidence from its pharmacological properties indicates promising potential in managing migraine symptoms. The plant contains a variety of bioactive compounds, such as flavonoids, alkaloids, saponins, and phenolic compounds, which demonstrate anti-inflammatory, analgesic, neuroprotective, and antioxidant effects. These properties suggest that Sesbania grandiflora may help address key mechanisms involved in migraine pathophysiology, such as neurogenic inflammation, vascular dysfunction, serotonin imbalances, and neuronal excitability. Preliminary research suggests that Sesbania grandiflora may reduce inflammation and modulate the trigeminovascular system, which plays a central role in migraine pain. Its anti-inflammatory effects may inhibit the release of inflammatory mediators like calcitonin gene-related peptide (CGRP) and substance P, both of which are involved in migraine attacks. Additionally, the plant's antioxidant properties may help protect neural tissues from oxidative stress, which has been linked to migraine triggers. Furthermore, the plant’s potential ability to stabilize serotonin levels and regulate vascular tone could help in reducing the severity and frequency of migraines. Sesbania grandiflora may also protect against neuronal damage associated with cortical spreading depression, a phenomenon linked to the aura phase of migraines. While these results show that Sesbania grandiflora may have therapeutic potential in migraine management, more robust and comprehensive clinical trials are necessary to definitively confirm its efficacy, safety, and long-term effects in treating migraines.
