Gunja1 is one among the Upavishas, which is effective in Kushta, Kandu, Vrana and indralupta in various dosage forms such as Taila, Churna, Rasa, Lepa etc. Shodhana is a procedure that converts a poisonous drug into a therapeutically very effective medicine.

Here shodhana of Gunja bija is done in Godugdha and kanji as per Rasatarangini and the its physico-chemical changes are analyzed.
