Milk Thistle Oil is used in its edible form (by drinking 1-2 tablespoons daily) for the regeneration of new tissues in the liver (along with artichoke oil). 

It regulates the function of the central nervous system. It is used for detoxification, anxiety, epilepsy, insomnia, hemorrhoids, asthma, ulcers, gallstones, and kidney stones.

Milk Thistle Oil is used either on its own or in combination with other base oils for even better results. Finally, it is important to know that base oils are essential in aromatherapy as they serve as the "carrier" to which essential oils will be added.
