Yavasa
Alhagi pseudalhagi
Yavasa (Alhagi pseudalhagi) is a plant drug, from the Fabaceae family. Flavonoids (isorhamnetin, kaempferol glycosides) undergo typical Phase II conjugation with low to moderate systemic bioavailability (~10-20%). Manna sugar (a natural exudate) is largely composed of saccharides that are absorbed as dietary sugars.

Published research
Literature indexed in PubMed that concerns this subject, grouped by study type. A paper appearing here is a record of what has been published, not evidence that the subject works, and laboratory or animal results do not transfer to people. Study titles link to PubMed so you can read the source rather than take our word.

Consult a qualified vaidya before acting on anything here. Ayurvedic practice is prescribed to a person, not to a condition: the same dravya is given, withheld or substituted depending on your constitution, your agni, the season and what else you are already taking. A page cannot know any of that. Self-prescribing from a reference is how the wrong preparation, the wrong dose or the wrong anupana gets used.
Educational reference only. Nothing on this page is medical advice, a diagnosis, or a recommendation to take anything. Traditional uses and research findings are reported as published, not as claims about what any product does. If you take prescribed medication, raise any interaction with the prescriber rather than acting on a page. See our editorial standards.
