Shakuyaku-kanzo-to is a Japanese herbal formula that is a part of the ever-evolving system of traditional Japanese medicine, called Kampo. A Kampo drug is a standardized and regulated multi-herb formula. Kampo formulas are an essential component of Japanese integrative medicine and are often given to patients alongside Western treatments in even the most mainstream of Japan's hospitals. Shakuyaku-kanzo-to is a Kampo formula made up of a blend of two crude drugs: shakuyaku (peony root) and kanzo (glycyrrhiza root, or licorice).
Due to its proposed effectiveness as a sedative, pain reliever and antispasmodic, shakuyaku-kanzo-to is prescribed in Japan to relieve calf cramps, menstrual and non-specific abdominal pain.
The herb is manufactured as prescription only in Japan by Tsumura®. The formula is usually taken by mouth in the form of capsules or tablets and the doses are higher than most Western medicines. Japanese patients often boil this formula into a tea. However, the smell and taste of such medication is not appealing to the palate of most Westerners. A qualified healthcare provider should be consulted before making decisions about therapies and/or health conditions.
Shakuyaku-kanzo-to has been used in Japan and China for muscle pain and skeletal muscle tremors, arthralgia, numbness, peripheral neuropathy and dysmenorrhea.
Scientific studies suggest that shakuyaku-kanzo-to effectively reduces the severity of peripheral neuropathy, arthralgia (joint pain) and myalgia (muscular pain) and muscle cramps.
Since shakuyaku kanzo-to consists of several herbs, it can potentially interact with other drugs, herbs or supplements. Therefore, a qualified healthcare provider should be consulted before making decisions about therapies and/or health conditions. Avoid if pregnant or breastfeeding.
