Standard Dosage: 10-20g in decoction, or applied externally. Cautions: Talc can cause granulomas in the rectum, vagina or wounds and prolonged external use has also been linked to ovarian (Wentzensen & O'Brien, 2021), stomach (Chang et al., 2020) and lung (Chang et al., 2017) cancer but other reviews contradict these findings (Goodman et al., 2020) suggesting this may only be an effect seen in rats (Prueitt et al., 2024). For safety it should therefore not be used for prolonged periods. It should also not be in inhaled as it can cause lung irritation and remain in the body for up to 40 years (Johnson, 2021). Mineral products are prohibited from use in the UK under the Medicines Act 1968 ch. 67 which restricts herbalists to the use of plant products only. It is generally substituted with Chi Fu Ling and Ze Xie.

Mu Xiang

Subsitutions:

This combination forms the main Summerheat clearing and Damp draining part of the formula so substitution could be attempted with Chi Fu Ling and Ze Xie (increase dose) to clear Heat and Dampness, Xiang Ru and Bai Bian Dou to clear Summerheat and drain Dampness plus Zhi Mu to clear Qi level Heat while protecting the fluids from excessive draining.

Preparation: Grind the ingredients into a powder and take with 9g with water or in a decoction of Sheng Jiang.

Actions: Expels Summerheat, clears Heat, promotes the resolution of Dampness, generates Yang fluids and augments deficiency of the Middle Jiao
