FORMULA EXPLANATION

Flex (SC) is formulated to relieve muscle spasms and cramps. According to traditional Chinese medicine, the etiology of muscle spasms and cramps is Liver yin and Liver blood deficiencies. Effective treatment, therefore, must focus on nourishing Liver yin and Liver blood deficiencies, activating qi and blood circulation, and removing stagnation.

Bai Shao (Radix Paeoniae Alba) tonifies Liver yin and blood to relieve spasms and cramps. Paeoniflorin, the active constituent in Bai Shao (Radix Paeoniae Alba), has potent analgesic, antispasmodic, and anti-inflammatory effects. Together with the harmonizing function of Zhi Gan Cao (Radix et Rhizoma Glycyrrhizae Praeparata cum Melle), they nourish and relax the tendons and smooth muscles. Hua Jiao (Pericarpium Zanthoxyli) and Dang Gui Wei (Extremitas Radix Angelicae Sinensis) are used to warming peripheral channels and collaterals and invigorate qi and blood circulation.

BACKGROUND
Muscle spasms and cramps are involuntary and sometimes painful contractions of the muscles. Spasms and cramps affect many muscle groups, including but not limited to the leg, calf, thigh, hands, arms, abdomen, and intestines. Common causes of muscle spasms and cramps include overuse or injury of a muscle, dehydration, electrolyte imbalance, excessive consumption of alcohol, specific disease state (hypothyroidism, kidney failure), and use of drugs (diuretics). Stretching and adequate intake of fluids with sufficient amounts of potassium are the best preventative measures for spasms and cramps. If necessary, herbs that relax the muscles can also be used.
