Medicinal uses
Hypoxis is promoted as an alternative medicine treatment for benign prostatic hyperplasia, but research has found no evidence of beneficial effect. Additionally, one study suggests Hypoxis alters the activity of cytochrome P450, suggesting that it may interfere with the effectiveness of other drugs or supplements, such as antiretroviral drugs.
