Kurabaka
Kurabaka is a substance used in the Ayurvedic materia medica. Flavonoids show moderate oral bioavailability. Bark tannins exert primarily local GI action with limited systemic absorption. Lipid-based formulations (Taila) enhance transdermal penetration of bioactives for topical applications.

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.

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.
