Harm score: 1 (Natural substances)
Salvadora persica, also known as miswak, siwak, meswak, arak, peelu, pilu, jhak or kayu, is a shrub or small tree native to Asia and Africa. This plant is very well known, especially in the countries of the Middle East and South Asia. It is particularly popular for its medicinal properties, where it is used, among other things, in traditional Arabic medicine, but also in oral hygiene. Its branches contain essential oils that have antiseptic properties and regular chewing of the plant prevents dental disease.
Another important characteristic of Salvadora persica is that it contains a lot of fluoride, which contributes significantly to the protection of tooth enamel. As a result, Salvadora persica extract is increasingly appearing in toothpastes, mouthwashes and special chewing gum. The bristly or rather fibrous end of the plant's branches, which gives it its characteristic appearance, can be used as a natural toothbrush. In some cultures, this method of brushing teeth is still commonly used. The wood of the Salvadora persica is the source of an essential oil with a distinctive flavour, which is also still used in perfumery for its specific aroma. The plant is thus used in many industries, from pharmaceutical to cosmetics.
