Psoralea corylifolia (Babchi) and its oil are called as Kushtaghni in Ayurveda which means remedy for treating skin diseases.
Numerous research done on the plant state that the presence of active constituent Psoralen in Psoralea corylifolia promotes pigmentation and support the stimulation of melanin pigments in the skin structure which in turn help in managing vitiligo. Pigment formation is much faster when the affected areas are exposed to sunlight and alternate sources of UV light. Scientific studies have also proven that Psoralen stimulates residual pigmentation and improves skin health.
Another study showed that Psoralen is a photoactive furocoumarin that binds to DNA when exposed to UV light to form photoproducts with pyrimidine base. This action inhibits DNA synthesis and causes decrease in skin cell proliferation. This inhibits excessive skin scaling and helps in managing psoriasis.
Cream containing Psoralea corylifolia can be applied onto the affected areas and exposed to sun or UV light for faster relief from the symptoms of auto immune disorders like Psoriasis and Vitiligo.
