Uses

Folkloric
- No recorded folkloric use in the Philippines.
- In China, decoction used for detoxification, as anti-inflammatory, and for treatment of sores and snake bites.

Studies

Air-Purifying Plant: Sansevieria trifasciata is in NASA's list of air-purifying plants, improving indoor air quality by passively absorbing toxins (formaldehyde, nitrogen oxides, and other indoor toxins).
Analgesic / Antipyretic: Study of ethanol and water extracts of Sansevieria trifasciata leaves showed dose-dependent and significant (P<0.05) increase in pain threshold in the tail-immersion test. The water extract showed not significant effect on brewer's yeast-induced fever in rat; however the EtOH extract significant reversed yeast-induced pyrexia.(2)
Insecticide / Antipyretic: Study evaluated the efficacy of insecticides on the growth of string beans. Study showed that Sansevieria trifasciata insecticides are as effective as commercial ones.(3)

Availability
Wild-crafted.
