Vanshlochan (Tabasheer) – Bamboo Silica (Bamboo Manna)


Vanshlochan (also known as Tabasheer, Bamboo Silica, & Bamboo Manna and spelled as Banslochan & Tabashir) is siliceous resin and bamboo exudate, which is a form of herbal silica obtained from female bamboo trees. Vanshlochan secretes from nodes of bamboo trees. It is collected from the female bamboo tree’s nodes for therapeutic uses, as used in Ayurvedic Medicine and Unani Medicine.

Vanshlochan vs. Tabasheer

Vanshlochan and Tabasheer were actual different things, but in Farsi language, Tabasheer is synonym of Vanshlochan. Vanshlochan is a bamboo exudate, which is now rarely available in the market. In market, Tabasheer (prepared from Curcuma Angustifolia, also called Tikhur & East Indian Arrowroot) is sold in name of Vanshlochan. (Reference: Acharya Priyavarata Sharma, Dravya Guna Vigyan, Part 2, Chapter 7, 258 Vansha – Bambusa Arundinacea Willd)

In Astanga Sangraha, Banshlochan and Tabashir are described as different remedies and description of both remedy is in same place. Nowadays, Tabasheer is taken as alternative of Vanshlochan.


Tabasheer is also less available and now adulteration becomes another problem for getting the original Vanshlochan. Artificially prepared Vanshlochan is now sold in Indian Market, which results in a huge loss of ayurvedic physicians and lovers.

The Artificial Vanshlochan is prepared from Sodium Silicate and Ammonium Silicate. These both chemicals are mixed in water. Then the mixture is leaved for drying. After drying process, the material obtained is sold as Vanshlochan.
