    By taste bAkucI is sweetish (primary taste); bitter (secondary taste).
    Post digestion vipAka of it is pungent (kaTu).
    The potency of psoralia as per BhAva PrakAsha is hot.
    DoShic Action:- Being tikta in taste and pungent in vipAka in association with rUkshatva (dryness) & hot potency – bAkuci expels and ameliorates kapha doSha.
    At the same time, the hot potency is capable of increasing the pitta doSha and reducing vAta doSha. The sara guna of pitta gets increased by regular intalke of bAkucI, there by resulting in sramsanam action causing elimination of pitta from the physical matrix, clinically speaking. The same sara guNa of the psoaralia altercates the viShTambha (obstruction) with in the pittavahana channels.Hence therapeutically as an Ayurveda physician, it gets used in clinical condition , of the diseases indicated for bAkucI observed in a patient – based on the following doshic equation pathologically,

    Charaka too states,KV-vrddhi_ P- kshaya doshic equationto be the pharmacodynamics of the seeds of the avalguja, upon the doshic matrix.बाकुची is capable of providing pigmentation in leucoderma patches. The usual method adviced in the classical texts regarding the usage of bAkuchI is – after subjecting the rugna (patient) to raktavisrAvana (blood letting therapy) and there by letting the vitiated doshAs from the shAkAdaya dhAtus (local dhAtus like rasa, rakta & mAmsa), the bAkucIbIja kaShAya with guDa as anupAna be given. Else the bAkucI tailam with honey  be given for pAnArtham. And later bAkuci with dhAtri & khadira sAra in the proportions mentioned as in the classical texts related to pharmacology (bhaisajya kalapanA shAstra) be given daily as a regular dosage.When the sphotAs (vesicles) gets manifested as the clinical effect of using the bAkuci in afore said forms of yogAs, it should started to be given along with takra sans salt, and rice mixed with takra (butter milk) without adding lavan (sans salt) be partaken as regular diet, until the whitish patches gets vanished and fresh pigmentation covers the entire lesion of leucoderma or vitiligo.Its is at this stage of occurence of blisters, the patients usually stop following the medication out of fear of having got some side effect of the medicine. But, in actual it is the therapeutic effect of the medicine which gets induced upon taking the bAkuci seeds, caused by the increse in the prAkrta pitta seated within the layers of the skin.The tikta and katu predominance in the psoralia seeds reduces the excessive kleda amsha (pathological moistness) by drying it, counteracts the the kustha (obstinate skin diseases) and the krmis (which usually enjoy thriving and reproducing in moist and dampness in affected portions of the human body). In addition it instigates the secretion of normal pitta underneath the skin. It is for these pharmacodynamics (Ayurvedically) of the bAkuci, it is being considered as RasAyana by many of the well experienced vaidyas, who rely up on it for treating kuStha, gambhIradhAtu gata KuSThAs (deep seated skin diseases, means whose pathology starts at the level of the dermis).When it is adviced as a nitya rasayana, the following mediums gets adviced to mix the bAkuci churna,  depending upon the dosha, desha and season – milk, ghee, butter, honey. Which ever of the above medium be selected, upon considering the required Ayurvedic clinical parameters, buttermilk and the rice with buttermilk sans salt is to be followed as pathyA (required dietetic formula).In dadru, gajakarNa, pAmA, sidhma etc skin manifestations bAkucibIja chUran mixed with takra is adviced as lepanam. In case the vesicles erupt, after it gets burst open, the normal hue of the skin gets manifestedSome Common useful Yogas of bAkucI :-bākucī cūrṇa

    Research Studies on Bakuci:-

    1. The furanocoumarins, which contain psoralens, promote pigmentation[i]
    2. It also alleviates boils and skin eruptions. The plant has blood purifying properties. It is used to treat itching red papules, itching eruptions, extensive eczema with thickened dermis, ringworm, rough and discolored dermatosis, dermatosis with fissures, and scabies[ii]
    3. Seeds are given in scorpion-sting and snake bite[iii]
    4. The major components psoralen and isopsoralen have antitumor, antibacterial, and antiviral properties[iv]
    5. It shows coronary vasodilatory activity[v]
    6. The seeds act as deobstruent and heal ulcer, heart troubles, and cure blood disorders and elephantitis[vi]
    7. The herb is cytotoxic, antimutagenic, and antirepellant[vii]
    8. Katsura et al proved that bakuchiol is a useful compound against oral pathogens and has a great potential for use in food additives and mouthwashes for preventing and treating dental caries. The cell growth of mutans was inhibited in a bakuchiol concentration-dependent manner and the growth of S. mutans was completely prevented with 20 μg of bakuchiol/mL.[viii]
    9. Bakuchiol, one of the major constituent of corylifolia, has been shown to possess a prominent cytotoxic effect on L929 cells in all cultures. It also showed cytotoxicity against cultured human cell lines, namely, A549, SK-OV-3, SK-MEL-2, XF-498, and HCT-15.[ix]
    10. The water-soluble extract containing bakuchiol has been found to possess hepatoprotective activity in tacrine-induced cytotoxicity in human liver-derived HepG2 cells. The EC50 value of bakuchiol was 1 μg/mL and of silymarin was 5 μg/mL[x]
    11. The alcoholic extract produced death of microfilariae and showed antimycobacterial activity[xi]
    12. It was observed that flavonoids, mainly corylin and bavachin, have osteoblastic proliferation-stimulating activity and thus might stimulate bone formation and act against osteoporosis.[xii]
    13. Chandhoke and Ray reported that isopsoralen showed tranquillosedative, anticonvulsant, and central muscle-relaxant properties in rats, mice, and rabbits.[xiii]
