Healing Properties and Warning

- Vermifuge: When applied as an enema, it eliminates oxyuridae (parasites) usually located in the anus and rectum, where orally taken medicines cannot act.
WARNING! In high doses, this plant can produce vomiting. It should be avoided in the case of gastroduodenal ulcers and during menstruation (it provokes uterine colic).
Killing roundworms is one of the primary values of quassia. If taken as an enema, it can kill pinworms. In addition, an infusion of quassia wood can treat dyspepsia, rheumatism, and fever. A bitter tonic for stomach ailments can be made by leaving water overnight in a glass cup of many quassia wood chips or in a cup made of quassia wood, resulting in a weak infusion that in a drink will help strengthen the stomach. Quassia tea is also believed to lessen the appetite for alcohol. In external applications, the plant can be used to rinse the scalp to treat dandruff.
After discovering the quassia amara, another similar tree was found in Jamaica with the same healing properties, however, more potent. This tree was called Jamaican Quassia (Picraena excelsa L.).
