In dealing with the elimination of waste and toxic substances from the body, the kidneys, liver and gallbladder can, over time, become overburdened. Planetary Herbals offers you STONE FREE, a unique blend of turmeric root, gravel root, dandelion root extract, ginger root, lemon balm leaf, marshmallow root, parsley root, dandelion root, and licorice root. These herbs have been used historically to support the kidneys, liver and gallbladder and promote healthy organ function. This comprehensive formula is twofold—it aids normal fluid elimination and bile production and assists with the body’s natural cleansing processes. Primarily detoxifying botanicals, the herbs in STONE FREE act to flush, cleanse and detoxify, ridding the body of mineral and other waste and fat-soluble toxins. Purifying Support for the Kidneys: Healthy kidney function involves the filtration of waste products (including various minerals) from the blood, and the excretion of liquid waste through the urine. Primary kidney supporting herbs - such as gravel root, parsley root, and marshmallow root - have traditionally been used to aid normal fluid elimination and general genitourinary health, thereby helping to ensure the smooth passage of urinary waste through the urinary tract. Bitter Substances and the Normal Flow of Bile: One of the liver's main methods of detoxification is in the manufacture and secretion of bile - a carrying agent for the elimination of toxic substances from the body. Stored in the gallbladder and then released into the small intestine, bile also serves in the digestion of fatty acids and absorption of fat-soluble nutrients; it emulsifies fats, and therefore is essential in the proper health of the gallbladder. However, if bile is not properly metabolized, it can mix with excess minerals, affecting its normal excretion functions.
