One of the main reasons to include ghee is because it contains butyric acid, which they say is essential to maintaining gut health. Our body makes butyric acid from the fiber we eat, so using ghee is a faster way to increase the butyric acid in the body.
Fermented tea (kombucha) also contains butyric acid, so adding this into a cleanse would give more butyric acid for the body as well.
Just FYE – butyric acid is what gives vomit its distinctive smell.
If they want to use something that may have actual health benefits, rather than just grapeseed oil, for preparing food, I’d use coconut oil.
Ghee has short chain fatty acids which don’t have to be broken down to be used for energy, and coconut oil has medium chain triglycerides which are used immediately for energy.
Ghee (they say) contains antioxidants – coconut oil also contains ferulic and p-coumaric acid which are purported to protect against free radical damage.
The lauric acid in coconut oil also is said to boost immunity and fight infection. It is antiviral and antifungal, which rids the body of fungal growth and helps rid the body of candida yeast infections, and other such conditions. The caprylic acid in coconut oil is also antifungal and helps this. Coconut oil also has capric, myristic and palmitic acids, which are anti-inflammatory and anti-microbial.
Coconut oil also contains vitamins E and K, as ghee does. Coconut oil also has iron in it.
So….. that would be my recommendation for a vegan method of an ayurvedic cleanse.
