Tabasheer
substance obtained from babmoo

Tabasheer (Hindustani: तबाशीर or طباشیر) or Banslochan (बंसलोचन, بنسلوچن), also spelt as Tabachir or Tabashir, is a translucent white substance, composed mainly of silica and water with traces of lime and potash, obtained from the nodal joints of some species of bamboo. It is part of the pharmacology of the traditional Ayurvedic and Unani systems of medicine of the Indian subcontinent. It is also an ingredient in many traditional Iranian and traditional Chinese medicines.
Purported benefits
Tabasheer is claimed to provide a variety of health benefits. It is variously regarded as an antipyretic, antispasmodic, antiparalytic, restorative and aphrodisiac.
Varieties
Tabasheer that has a blueish tint (usually called neel or neelkanth) is considered superior to tabasheer that has the "more plain" yellow or white color.
Extraction
Not all bamboo stems contain tabasheer. Likely candidates are found by shaking bamboo stems, which can make the mineralized tabasheer inside produce a rattling sound. These stems are split open to extract the tabasheer.
History
Although a part of the ancient Ayurvedic system of medicine, it has been postulated that the use of tabasheer originated in the Adivasi aboriginal tribes of India.
This brief starts where responsible research should: with the source description of “Tabasheer” as substance obtained from babmoo. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as substance obtained from babmoo. Its deeper value depends on whether names, dates, institutions and citations support that framing.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Aug 25, 2025. The linked authority identifier is Q1642659. None of the 0 selected statements returned an explicit reference.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
