What traditional systems uses this plant?
This plant, Ammi visnaga, has been utilized across various historical medical traditions for its potent pharmacological properties, specifically to treat ailments involving the cardiovascular and urinary systems. In Egyptian folk medicine, practitioners historically employed the plant to address various internal maladies and digestive issues. Moroccan folk medicine also incorporates this species, frequently using its seeds or roots to manage specific inflammatory conditions and parasitic infections. These traditional applications often focused on the plant's ability to relax smooth muscles, a characteristic now scientifically linked to its khellin content. This long history of human use underscores its significance in both regional herbalism and early pharmacological experimentation.
According to a study published by "Journal of ethnopharmacology", the content of the furanochromones khellin and visnagin in the organs of Ammi visnagia (L.) Lam. has been examined at different developmental stages. Unripe fruits are the richest in both of these chromones. However, the collection of ripe dry fruits is utilized in Egyptian folk-medicine. This method of collection seems more reasonable because the fruits might not undergo degradation processes during desiccation and storage.

What medicinal compounds this plant contains?
This plant contains the medicinal compounds visnadin, visnagin, khellin, khellol, and linaalool. Visnadin and visnagin are furanocoumarins that are primarily recognized for their potent vasodilator properties. The compounds khellin and khellol belong to the furochromone class and contribute to the plant's pharmacological activity. Additionally, the monoterpene linaalool is present and adds to the overall chemical profile of the species. These various substances work together to provide the therapeutic effects traditionally associated with the plant.
According to a study published by "Planta medica", the most active lipophilic extract of Ammi visnaga fruits, known as DAB 10, was investigated using K+ (60 mM)-depolarized guinea-pig aortic strips. The effective principles identified within this plant are visnadin, khellin, and visnagin. Among these, the dihydropyranocoumarin visnadin was determined to be the most active compound. In selectivity tests against norepinephrine (100 microM)-induced contractions, the furanochromenes khellin and visnagin inhibited spasms to a similar extent. However, visnadin's activity was significantly higher against K(+) spasms, suggesting its involvement in a calcium channel blocking mode of action.
The primary medicinal compounds of this plant are shown in the list below.
- Visnadin
