Clinical evidence
Small trials suggest potential benefits for skin health and antidiabetic effects. A 2021 trial showed that a topical extract reduced itching and redness in people with mild eczema. A 2018 study showed that leaf extract reduced fasting glucose in diabetic rats. More robust clinical trials are needed to confirm these effects.
