Shodhana (If Required): Bakuchi seeds needs to be purified before oral intake or applied locally on skin. It has erosive nature so may cause blisters formation on skin when applied directly. Three procedures, viz. Nimajjana (immersion), Prakshalana (washing with water), and Bharjana (roasting), were mentioned for pretreatment of Bakuchi. Pretreatments are noted as soaking of Bakuchi fruits in Gomutra (cow’s urine) or Ardraka Swarasa (juice of Zingiber officinale Rosc.) for 7 or 21 days or Bibhitaka Kwatha (decoction of Terminalia belerica Roxb.) for 1 night and Bharjana (roasting) in Ghee. Blisters occur because of the presence of furanocoumarins like psoralen in formulations, which holds Bakuchi. Pretreatment performed on Bakuchi fruits may derive newer chemical moieties, further rendering it helpful to minimize adverse drug reactions, increase the efficacy of Bakuchi or its containing formulation, and further break the pathogenesis of the disease.
Bakuchi, the skin remedy, holds significant importance in Ayurvedic medicine, especially in managing skin disorders and promoting hair health. Its unique properties make it a valuable herb for maintaining healthy skin and hair.
