Bakuchi

Psoralea corylifolia contains psoralen (a furocoumarin that intercalates DNA upon UV exposure, used in PUVA therapy) and bakuchiol (a meroterpene phenol with retinol-like activity). A double-blind RCT (n=44) found 0.5% bakuchiol cream comparable to 0.5% retinol for reducing wrinkles and hyperpigmentation after 12 weeks, with significantly better tolerability (less scaling/stinging). Bakuchiol shows antioxidant effects, increases collagen (COL1A1, COL7A1), and enhances wound healing. For vitiligo, psoralen-containing preparations have traditional use and case study support, but robust RCT evidence is lacking. Preclinical data suggests bone-protective effects via prenylated isoflavones and catecholamine-modulating antidepressant properties.

Aloe vera is a succulent plant used topically for burns/wounds and orally for constipation. B-grade evidence for blood glucose in prediabetes, canker sores, and oral health. However, many clinical trial results are conflicting. IMPORTANT: Topical and oral forms have very different uses. Oral aloe latex (containing anthraquinones like aloin) is a potent laxative but can cause electrolyte imbalances with long-term use - FDA warning. Topical gel is generally safe. Evidence for burns and wound healing is mixed despite popular use.
