Vajikarana (aphrodisiac therapy)

The introduction says vṛṣa-cikitsā, the eighth limb of Ayurveda, means vājīkaraṇa therapy.

The commentary glosses vṛṣya as what increases desire and produces semen, and the author promises to describe the aphrodisiac substances with their characteristics later, in the Yogarāja section.

Bowers of creepers full of blossoming flowers, which delight the mind and increase joy, are fit for recreation; they please the senses and are mostly the causes of desire in the amorous. The verse adds what is pleasant to the eyes, touch, ears and nose.

A beautiful young woman wearing becoming clothes and ornaments, slender-waisted, with high full breasts and shapely hips, is said to arouse men.

Whatever is cooling, unctuous and sweet is called vṛṣya (increasing semen and arousing desire) by the great sages.

Eating goats, deer and boars in the hope of becoming as sexually vigorous as these animals is called laughable: goats never eat goats, and these animals are said to owe their virility and many young to eating trees, grasses, shrubs and herbs.

Wild animals that eat no honey, liquor or meat, such as elephants, gavaya, bulls, spotted deer, goats, deer, ruru, chamara deer and boars, living on land, in water, on mountains, in trees and in forests and eating grasses, shrubs, creepers and leaves, are said to have firm, strong bodies, strength, virility and nourishment, many young and mates, and to be very amorous; while lions, tigers, taraksha (glossed as an animal with a thorny body), leopards (dvipi), cats and others that eat only meat lack dhatus, are childless and mate once or so a year, as Nimi too is quoted as saying.

Those who eat the meat of goats, deer and boars in the hope that, since these animals mate so much, their own bodies will become as full of dhatus, are called laughable: goats have not eaten goats, deer have not eaten deer, nor boars boars, to become robust; these animals calm their diseases by eating many kinds of trees, grasses, shrubs, plants and creepers as medicines, and so stay content, of pure dhatus, robust and with many young.
