Description
What is it
Jamun — Syzygium cumini, the Indian Blackberry or Java Plum — is one of the most storied trees of the subcontinent. “Tamil calls it Naval, Sanskrit Jambu — the classical name from which the Hindi jambul and the English jambolan both descend; its purple fruit stains the summer, and its leaf, bark and seed have all been valued across Siddha and Ayurveda for centuries. Ayurveda classes the leaf as kashaya — astringent — and has long turned to it for digestive and metabolic wellness. We take the pure whole leaf, carefully dried and milled, and present it single-ingredient in a vegetarian capsule — the traditional wellness leaf, clean and ready.
What Makes This Different
- Pure whole leaf, single ingredient. Whole Syzygium cumini leaf powder — no fillers, binders, flow agents or extract dilution.
- Leaf, not seed. Most jamun products use the seed; the leaf is its own tradition, and it’s what we use — and say so.
- The astringent leaf, made easy. Jamun leaf is tannic and astringent to take as-is; the capsule delivers it clean, with no taste to negotiate.
- Certified base: FSSAI Central Licensed, GMP compliant, ISO 22000.
What It Does
- One of Ayurveda’s most storied trees. Known as Jambu in Sanskrit and Naval in Tamil, jamun has been woven into Indian medicine and daily life for millennia — leaf, bark and fruit alike.
- A traditional astringent for digestive comfort. Jamun leaf is naturally astringent (kashaya), long valued in tradition for digestive comfort and everyday gut balance.
- Naturally antioxidant-rich. Among the plant’s parts, the leaf carries the highest phenolic content and antioxidant activity in laboratory testing (DPPH, FRAP, ABTS), tied to flavonoids such as myricetin and quercetin (in vitro).
- Traditionally valued for metabolic wellness. In Ayurveda and Siddha, jamun has long held a place in traditional approaches to everyday metabolic balance.
- Emerging angle — a myricetin-rich profile. Myricetin, the leaf’s predominant flavonoid, is an active area of antioxidant research (in vitro).

How to Take It
Take one veg capsule twice daily with water, with or after food, as part of your daily routine. Best enjoyed steadily as part of a balanced diet rather than as a short course. If you are pregnant or breastfeeding, giving it to a child, or taking prescription medication, consult a healthcare professional before starting any new supplement.
