Garlic Benefits According To Ayurveda
According to Ayurveda, garlic (Lashuna) possesses five tastes, sweet, sour, pungent, bitter and astringent (pancharasa). It doesn’t possess the salty taste. It is unctuous (snigdha), heavy (guru), strong (tikshna), induces mobility (sara) and has a hot potency (ushna virya). Its post-digestive effect (Vipaka) is pungent (Katu).
It is nourishing (balya), improves eye vision (Chakushya), ignites the digestive fire (deepana), acts as a heart tonic (hridya), brain tonic (medhya), aphrodisiac (vrashya), rejuvenator (rasayana) and antimicrobial (jantughna). It purifies the blood (raktadoshhar), improves complexion (varnya), aids in healing of fractures (bhagnasandhankar), balances Vata and Kapha dosha but increases Pitta dosha.1
Based on its action, garlic is also known as mahoushadha. That means, it treats disorders due to Vata imbalance. It is able to have positive effects on many diseases.
The ancient Indian Ayurvedic physician Kashyapa said that garlic is born from nectar. What he meant was, it has a rejuvenating (rasayana) property. This herb clears the channels (srotas), produces sperm and spermatic fluid (shukra) along with ovum and ovarian hormones (shonita). It also nourishes the breasts.2
In the classical Ayurvedic text book Charaka samhita, this herb has been indicated in skin diseases (kustha, kilasa), disorders due to Vata (vata roga) and in increasing sperm count and sperm motility (vrushya).3
Another ancient Ayurvedic physician Vagbhata considered garlic (lashuna) the best Vata pacifier. He emphasized that garlic is the best remedy for vataja disorder. It acts as a rejuvenator to remedy all types of obstructions (avarana) except those caused by Pitta dosha and blood tissue (rakta).4

It has been suggested that individuals on allopathic anticoagulant medicines should be cautious while taking garlic because of its antithrombotic properties. 34
