Vanshlochan (Bamboo manna) Information, Properties and Benefits

Vanshlochan is extensively used in Ayurveda as a stimulant, sweet, cooling, tonic, expectorant, haemostatic, aphrodisiac, diuretic and anti-cough. In Sanskrit, Bans or Vansh is synonym for Bamboo and Lochan means eyes. So the discharge of bamboo eyes is known as Vanshalochan.

Vanshlochan is siliceous concretion discharged from the joints of female bamboo (Bambousa arundinacae) plant and generally found inside the hollow stems. It is white-bluish, hard, opaque and found as irregular fragments. It absorbs great deal of water but does not get easily dissolved in water. It is known as Tabasheer in Unani and Bamboo manna in English.

Vanshlochan is effective in debility, impotence, male sexual disorders, cough, asthma, bronchitis, burning sensations, diseases of the blood, tuberculosis, leprosy and fever. It is added in composition of numerous compound prescriptions used for affections of the lungs.

Nowadays, it is rare to found genuine Vanshlochan in the market, as it is very difficult to procure, costly, and naturally found in low amount. So as a substitute, synthetic Vanshlochan is routinely used in preparation of Ayurvedic medicines. Sometimes the starch of Arrowroot (Maranta arundinacea) and East Indian Arrowroot, Tvakshira, Tvakshiri (Curcuma angustifolia) are also used as substitute of Vanshlochan. Of course, the composition, properties and health effects of Genuine and Synthetic Vanshlochan differ greatly.
