Customs and Traditions –
Styrax benzoides is a plant from which a resin is obtained which, in the air, tends to solidify into a rubber.
The resin is widely used in perfumery, cosmetics and pharmaceuticals, mostly for external use.
It has excellent odorous properties, it is in fact an excellent perfume riser and an effective preservative of some fatty substances, which prevents oxidation. It is therefore perfect for aromatherapy.
The cosmetic industry also takes advantage of its valid astringent and, above all, depigmenting properties, with products to lighten freckles and skin spots in general. Cosmetic preparations containing benzoin are used when you want to obtain a lightening effect on reddened skin, but also as a deodorant and purifying. These latter prerogatives are also exploited in toothpastes and mouthwashes.
In the pharmacy it enters the composition of preparations useful for disinfecting small wounds of the skin and mucous membranes, for chilblains, breast fissures and burns.
The resin is also a specific remedy for some minor respiratory diseases, using it in mother tincture.
The tincture can be used for respiratory diseases but also to perfume and purify environments.

Preparation Method –
Styrax benzoides resin can be used as a mother tincture; in fact, just dissolve a few drops in boiling water and do balsamic and expectorant inhalations in case of colds, throat irritations, catarrhal coughs.
The resin can be found on sale in herbalist’s shops or in specialized shops.
The mother tincture is simple to prepare. The resin is finely ground in a mortar and macerated in alcohol for food use for 10 days, shaking often. The proportion is 20 g of resin in 100 ml of alcohol. At the end of the maceration period, it should be filtered and stored in dark glass bottles.
For cosmetic use, for reddened skin and freckles, dissolve 1.5 g of tincture in 100 ml of rose water. The product thus obtained is called Venus milk and is applied to the affected parts with a cotton swab.
