Hu Tao Ren (walnut)- does funtion 2,3,4 and also moistens the intestines. (sweet, warm, and enters kidney, lung, large intestine channels)

*These herbs are almost always used together although Bu Gu Zhi could almost entirely replace all the funtions of Ge Jie with the exception of Hu Tao Ren tonifying the lung more.
* this substitution is warm-very warm and there is no salty quality however in the commentary of the Materia Medica it states that ge jie is "strongly warming to the kidney yang". If you patient has an issue with heat you could also add Bo He (mint) to clear and disperse heat and circulate lung qi to treat wheezing and coughs.

If you have any suggestions please comment!

Modern synthetic products to reduce fever: aspirin, acetaminophen, Ibuprofen

Research in the 1990's by Paul But phD, professor at the Chinese University of Hong Kong, performed experiments to test the effectiveness of rhino horn and some of its alternatives. He found that rhino horn, or high doses of buffalo horn, could reduce fever and counter toxins, as could a combination of herbs without any type of horn. Based on this study they found Rehmannnia glutinosa (Sheng Di Huang) and Coptis chinesis (Huang Lian) as acceptable botanical substitutes.
A survey of herbal practitioners in 2002 found that Sheng Di Huang was the most common botanical substitute for Rhino horn.
Botanical substitutes have added benefits because the provide antibacterial and anti-inflammatory properties in which Rhino horn did not.
Of course there are modern synthetic products such as aspirin, acetaminophen and ibuprofen which alleviate fevers that are easily accessible and affordable too.
