Tamarind is a fruit that is popular in the foods of Southeast Asia, North Africa and India.
I have discovered a simple tea that brings tremendous relief to gallstone pain and is an all-around healthy drink to boot. Flaxseed Tea. All you have to do is get your hands on a bag of golden flax seeds from the healthfood store. I found adding a stick of cinnamon while it steeps adds a nice flavor.
Another good remedy for gallbladder attack is put 2 cups of water to boil, add 1tbs. Of flax seed, boil for 5 min. Boiling leeches the fs oil out of the seed and it will soothe an attack. It is tasteless so you can add a little cinnamon or sweetener.
