Synopsis

Source of validity: Traditional
Rating (out of 5): 2

Soapberry (Sapindus spp.), commonly known as soapnut, has a long history of traditional use as a natural insect repellent, particularly in regions of Asia and the Indian subcontinent. The fruit contains saponins, natural surfactants that produce a soapy lather and are thought to have insecticidal properties. Traditionally, soapberry extracts and powders have been used to wash hair and skin, partly to deter lice and other pests. Additionally, soapberry water has been sprinkled around homes or used in cleaning for its purported ability to repel insects such as mosquitoes and ants.

Despite the widespread traditional use, there is limited scientific research specifically validating soapberry’s effectiveness as an insect repellent for humans. Laboratory studies have shown some insecticidal activity of saponins against agricultural pests and certain insects, but robust clinical trials or entomological studies confirming its efficacy as a topical repellent are lacking. Thus, while historical and ethnobotanical records support its traditional use, scientific validation is not strong at this time.
