I've been having revelations around my liver lately that I thought I'd share with fellow Pitta types. (I'm actually Pitta-Kapha.)
Despite not having any Kapha in my mind-body constitution, I've long struggled with weight and have a life-long history of dieting. In this past month, however, I've inadvertantly dropped several pounds without changing my lifestyle, save for one addition to my health practice: cleansing my liver. (My naturopath has put me on liver cleansing herbs, and advised several cups of dandelion tea every day plus monthly colonics.)
The liver is a filter that manages fats and toxins coming through the body; metaphysically, it is the seat of anger, and anger is a Pitta manifestation (fire). Anger (even suppressed anger or passive aggressiveness, etc), toxins (drugs, pollutants, etc), bad fats (hydrogenated, saturated, rancid, deep frying, etc), all contribute to overloading this beautiful, hard working organ. In cleansing it of toxins, it can better process fats in the body (hence the weight loss). In dealing with anger, I believe we can also cool the fiery liver to also help it function better.
In all, love your liver. Give it love, treat it well, address anger issues. Pitta is the fire of transformation, a power that we can choose to use for great creations, or for (self-) destruction.
