Siwak or miswak are mentioned in India’s ancient Manu laws, the Koran, Buddhism, and the Talmud. These traditional toothbrushes are pencil-sized branches or roots cut from local trees, such as the Neem tree (Azadirachta indica) and Arak tree (Salvadora persica), that contain compounds beneficial for reducing plaque and gum inflammation. The chewing stick continues to be used by millions of people today in sub-Saharan Africa and in Islamic and Hindu cultures, as a means of maintaining oral hygiene.

Neem, Siwak or Miswak chewing stick
A chewing stick can be prepared for use by removing about half an inch of bark from one end and chewing the exposed plant bers. When the softened bers fray into thinner “bristles,” they are rubbed against the teeth and gums.
