Ghee is the remaining oil. The stuff you skim out are the milk solids. :)
I have cold hands and feet too, and cannot eat a lot of raw foods. If I do have a salad, I usually pair it with a soup or I have to take a hot bath afterwards! LOl! And I can only eat salad with a heating dressing, like honey-mustard. When you make it from scratch it's the BEST dressing in the WORLD LOL! I'm just too Vata for raw foods. I think people with constantly peeling/chapped lips should not eat raw foods (weak spleen).
You can be a Pitta but have a Vata disorder that requires things that would normally aggravate Pitta. It's a puzzle. If you sweat easily, have insomnia or hives, then cayenne may be contraindicated, but otherwise, it really helps with circulation.
Cold extremeties is usually due to poor circulation, weak liver, imbalanced electrolytes, and even strained kidneys. Try eating 1/2 a tsp of good Sea Salt
- just eat it, all at once, and see if you get a head rush. That lets you know you've been low on it, that and excessive saliva. Then see about strengthening the liver with herbs etc.
