Nasya that holds back age

Seeds of bibhitaki, white sesame, kanguka (the commentary: phul priyangu) and ari (a kind of khadira) are each impregnated three times in turn with the juices of shirisha bark, koranta, bhringaraja and nili; the powders of the impregnated seeds, in equal parts, are rubbed with boiled water and the oil is pressed out. Nasya with these oils is said to keep a person always young as he is.
