What are bishop's weed supplements?

Bishop's weed (Ammi majus) is an annual plant in the Apiaceae family, often cultivated for its attractive flowering stems. It is also a commonly used spice in India.

Bishop's weed contains psoralens, which are substances that react with ultraviolet (UV) light and darken the skin. Psoralens are currently used together with UV light therapy to treat skin disorders such as psoriasis and vitiligo. Oral 8-methoxypsoralen, a drug made from bishop's weed, has been described as the drug of choice in photochemotherapy for vitiligo and psoriasis.

Early evidence suggests that psoralen compound 8-methoxypsoralen (8-MOP) from Ammi majus may help treat vitiligo (leukoderma). However, case reports also mention potential phototoxic skin damage, phototoxic dermatitis, and pigmentary retinopathy caused by Ammi majus.

There is currently insufficient evidence available in humans to support the use of Ammi majus for any medical condition. High-quality human studies are needed before any strong conclusion can be made about its safety and effectiveness.
