Pharmacological Actions:

The seed of Psoralea corylifolia L. (PCL), a well-known traditional Chinese medicine, has been applied as a tonic or an aphrodisiac agent and commonly used as a remedy for bone fracture, osteomalacia and osteoporosis in China.2

Bakuchi is Shleshmapittahara; its primary pharmacological actions are summarized as under:


Central Nervous System: 

i. Psoralidin, an active component in seeds, possesses potent antidepressant-like properties that were observed to be mediated via the monoamine neurotransmitter and the hypothalamic-pituitary-adrenal (HPA) axis systems.3

ii. Psoralen possesses potent antidepressant-like properties which were at least in part mediated by improving the abnormalities in the serotonergic and the HPA axis systems.4

iii. A seed isolate Delta(3),2-hydroxybakuchiol (BU) can inhibit dopamine uptake in dopamine transporter (DAT) transfected Chinese hamster ovary (CHO) cells, and dopamine reuptake blockade may provide an alternative approach for ameliorating parkinsonism. BU acts by protecting dopaminergic neurons from MPP(+) injury and preventing against MPTP-induced behavioral and histological lesions in the Parkinson's disease (PD) model, possibly by inhibiting monoamine transporters, which suggests that BU could be meaningful in PD treatment.5


Digestive System : 

i. Psoralea corylifolia L. demonstrates strong anti-Helicobacter pylori activity.6

ii. The seed extract inhibits ROS production and mitochondrial dysfunction induced by oxidative stress in hepatocytes.7


Endocrinal System : 

i. Possesses synergistic antidiabetic effect when used with Methi seeds.8


Cardiovascular System : 

i. Exhibits anti-platelet activity.9


Musculoskeletal System: 

i. It might be a potential candidate for treatment of postmenopausal osteoporosis because orally administrated Bakuchi extract can decrease urinary calcium excretion and decrease serum osteocalcin in ovariectomized rats, resulting in positive effects on bone mineral density as well as bone formation. 10

ii. Buguzhi (Bakuchi) extract in collagen matrix has the effect of increasing new bone formation locally in vivo. Buguzhi extract in collagen matrix can be used as a bone graft material.11


Skin and Hair : 

i. The seed extract exhibits significant antifungal activity.12

ii. Babchi oil is used because its chief constituent 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 cell proliferation. Moreover, babchi oil, in addition to providing psoralen, also acts as an oily phase for microemulsion system. The presence of surfactant and cosurfactant increases the permeation.13


Others : 

i. Psoralen and isopsoralen contribute to anticancer effect of P. corylifolia L.14

ii. Psoralidin may be useful as a potential lead compound for development of a better radiopreventive agent against radiation-induced normal tissue injury.15

iii. P. corylifolia has protective effects against oxidative stress-induced retinal damage, and may be considered as an agent for treating or preventing retinal degeneration. 16

iv. The plant extracts have been reported to possess antibacterial, antitumor, antioxidant, anti-inflammatory, antifungal and immunomodulatory activity. 17

v. Psoralen is a bone-modifying agent and a potential therapeutic to treat patients with bone metastases. 18

vi. Psoralidin, bakuchicin, psoralin and angelicin, isolated from the seeds of Psoralea corylifolia, showed significant antibacterial activities against a number of Gram (+) and Gram (−) bacteria. 19
