A doctor who decided
to bottle her clinic.
Chandayu was not built in a lab by marketers. It was built in Vavuniya, Sri Lanka by Dr. Hashani Perera — an Ayurvedic physician who kept being asked by patients to bottle the same herbal formulas she was prescribing.

Dr. Hashani Perera
BAMS · MSc Food & Nutrition
Formulated by a doctor.
Not a marketer.
During her internships at six Sri Lankan hospitals — covering ENT, Gynecology, Pediatrics, Surgery, and burn care — Dr. Perera noticed a consistent gap: patients needed safe, effective herbal support between clinic visits, but could not find formulas they could trust.
Chandayu began as a clinical solution. The same formulas she prescribed. The same standards she trained for. Now available to anyone who wants genuine Ayurveda — not wellness theatre.
"I formulate the way I prescribe — with full evidence, full transparency, and nothing to hide."
Research that backs every formula

Doctor-formulated
Every formula is designed by Dr. Hashani Perera BAMS, not a marketing team.
Full ingredient disclosure
We list every ingredient. No hidden synthetics, no misleading names.
Slow-crafted in Sri Lanka
Made in small batches in Vavuniya by Chandayu Ayurveda — fully herbal, fully honest.
Born at the crossroads
of two civilisations.
Chandayu is made in Vavuniya — a town that sits exactly between Anuradhapura (the ancient Sinhala Buddhist capital) and Jaffna (the heart of Tamil culture). For centuries, both traditions have shared this land and its remarkable plants.

The Sinhala Ayurvedic lineage — "Country Medicine" — stretches back over 2,500 years to the ancient hydraulic civilisation of Anuradhapura. The kings of this great city built vast irrigation tanks (wewas) that sustained a thriving dry-zone civilization, and with it, an indigenous pharmacopoeia of healing plants unique to this land.
“The Anuradhapura Mahavamsa chronicles, written in Pali, document herbal medicine practices dating to 400 BCE — centuries before modern pharmacology.”
