Apocynaceae · leaf
Gymnema
Gymnema sylvestre
Ayurvedic leaf (gurmar, 'sugar destroyer') mapped to modest human glycemic trials. Evidence is human-level but not definitive disease modification.
Safety first
Leaf can blunt sweet taste and has human glucose-parameter trials. It can add to hypoglycemia with diabetes drugs and is not a substitute for diabetes care.
Tradition vs trials
Traditional record. API and Ayurvedic practice use the leaf in kapha/madhumeha-type metabolic patterns. That mapping is traditional.
Trial literature. Small to moderate human trials report changes in fasting glucose or sweet-taste perception. Products and gymnemic-acid assays vary.
Practical ranges
Educational ranges — not a prescription. Culinary use is not an extract.
leaf extract
Human glycemic trials often use a few hundred milligrams of extract (standardized to gymnemic acids) daily; crude-leaf traditional amounts differ — not a prescription
Ayurvedic Pharmacopoeia of India (API) — Educational range only — not a prescription. A licensed clinician individualizes product, dose, and duration.
