The Styrax paralleloneurum is a plant that we find above all in Malaysia and Java where it is present both in the natural and cultivated state, both for the wood and for the resin. This plant is the source of white benzoin.
The extracted resin has a balsamic effect both for the upper respiratory tract and for intestinal regularity.
It is an expectorant, disinfectant and antiseptic. It is used to treat eczema, boils and chilblains.
It is also added to toothpastes for the treatment of oral conditions.
Some people owe it directly to the skin to kill germs, reduce swelling, and stop bleeding from small cuts. Benzoin is also used topically for skin ulcers, pressure sores and cracked skin. In combination with other herbs (aloe, styrax and tolu balm), benzoin is used as a skin protector. This combination is known as a “compound benzoin tincture”.
In addition, benzoin is used to treat hoarseness (laryngitis) and other respiratory diseases.
It is also used in the manufacture of drugs.

Preparation Method –
From Styrax paralleloneurum, through incisions in the trunk, a resinous liquid gushes out which, once dried, is marketed as an aromatic incense called white benzoin.
It is used by people both orally for swelling (inflammation) of the throat and airways and for other uses.
