Nirgundyadi Thailaya is a classical Ayurvedic medicated herbal oil, produced by Wickramarachchi Laboratories at their facility in Waliweriya, Gampaha, Sri Lanka. The formulation draws directly from the Ayurvedic classical text 'Sarvaroga Chikitsa Ratnam', placing it within a tradition of documented herbal preparation that predates modern pharmacy by centuries. This is an external-use product only.
The oil brings together several well-regarded herbs from the Ayurvedic canon. Nirgundi (Vitex negundo) gives the formulation its name and anchors the preparation, alongside Bala (Sida cordifolia), Gulooochi (Tinospora cordifolia), and Aswagandha (Withania somnifera). These herbs are combined to produce a medicated oil in the classical 'Thailaya' format — a preparation method in which plant materials are processed into an oil base, concentrating their properties for topical application.
Wickramarachchi Laboratories has been manufacturing Ayurvedic preparations since 1972, and the brand's packaging carries the note '40 years of excellence' — a reference to their longstanding place in Sri Lankan Ayurvedic production. The facility holds GMP certification, and the product is registered under Sri Lanka's Ayurveda Drugs Act (Registration No. W7480). The range now extends to more than 200 Ayurvedic products, with this oil among the more recognisable in the catalogue.
Each bottle contains 28 ml of the medicated oil, presented in a glass bottle sealed with a gold metal screw cap — a format that keeps the preparation stable and easy to dispense in small, controlled amounts. The bottle is compact enough to sit on a bathroom shelf or travel with ease.
This product is for external use only. The traditional method of application is to apply the oil to the relevant area, allow it to rest for ten to fifteen minutes, and then wash off with lukewarm water. It may also be applied shortly before bathing. Use should follow the guidance of a qualified Ayurvedic practitioner.
