Recently, I had noticed the positive effect of sesame oil on my skin, so I have looked in my fav book and see what I have found.
Sesame seeds are a rejuvenative tonic for Vata constitution and for the bones and teeth. The black seeds are as they contain higher amounts of solar energy. A confection of the seeds can be made with one part sesame seeds, one half part shatavari (if available, its Indian herb), with ginger and raw sugar added to taste. One ounce of this mixture may be taken daily.
Sesame oil can be used in the same way as the seeds. It is similar in properties to olive oil. With equal parts lime water, it can be applied externally for burns, boils and ulcers. Prepared with small amount of camphor, cardamom and cinnamon, it can be applied to the head for migraines or vertigo. The powdered seeds can also be used externally as a paste.
Sesame seeds are sattvic and produce sattvic tissues in the body, and so are a good for yogis, one ounce per day.
