Ophicalcite (hua rui shi)
What is ophicalcite? What is it used for?
Ophicalcite is a type of metamorphic rock similar to serpentine marble. The most common color of ophicalcite is white (due to its high calcium content), although a green version of ophicalcite is also known to exist. When used in herbal preparations, the stone is prepared by being cleaned, burned, then ground into a type of powder.
According to the principles of traditional Chinese medicine, ophicalcite has sour, astringent and neutral properties, and is associated with the Liver meridian. Its main functions are to stop bleeding and to release stagnation. Among the conditions that ophicalcite treats are vomiting and nausea, excessive bleeding caused by injuries.
How much ophicalcite should I take?
The typical dosage of ophicalcite is between 10 and 15 grams, usually taken orally with other items such as notoginseng and carbonized hair as part of a larger herbal formula. Larger amounts can be applied directly to the skin to treat external injuries.
What forms of ophicalcite are available?
The most common form of ophicalcite is as a powder, which can be applied directly to the skin. Ophicalcite is also a component of many popular formulas.
What can happen if I take too much ophicalcite? Are there any interactions I should be aware of? What precautions should I take?
Ophicalcite should not be taken during pregnancy, or given to patients with a weak constitution. As of this writing, there are no known drug interactions associated with ophicalcite. As always, make sure to consult with a licensed health care provider before taking ophicalcite or any other herbal remedy or dietary supplement.
