The drug (raw gum) is the highest grade and our tincturing process uses the finest odourless food grade alcohol only. Absolutely no synthetic plasticisers, denaturants or diluents are used, resulting in a totally natural product by ISO 9235 standards. This is the gold standard of benzoin extracts and every care has been taken to ensure consistent excellence in every drop. In addition to being a perfumery material, Benzoin Siam Tincture was a starting material for Friar's Balsam, a medicinal compound invented in the 1760s by Dr Johua Ward who combined it with smaller amounts of styrax resin and the bitter aloe ferox (a plant related to aloe vera). Fraterworks' Benzoin Siam Tincture is not produced in a food safe or pharmaceutical environment and as such is not be taken internally.
