In the UK inducing vomiting is not considered an appropriate treatment strategy meaning that Gua Di would have to be replaced with a downward moving Phlegm and Food Stagnation moving formula instead such as Zhi Zhu Wan or Bao He Wan. It is included in this list for reference only, to demonstrate the principle.

Preparation: Grind equal amounts into a powder and take 1-3g at a time with a warm decoction of Dan Dou Chi. If vomiting does not ensue increase the dosage. If it still does not work then tickle the throat with a feather or cotton swab.

Actions: Discharges Phlegm or Food Stagnation through vomiting

Contraindications: Caution should be taken with weak patients due to the ease with which Gua Di can injure the stomach. If vomiting does not cease then administer 0.3-0.6g of Ding Xiang.
