peony and licorice

[Guest guest]

There is one medline entry for " shaoyao gancao tang " and none for " shao

yao gan cao tang " and one for " peony and licorice decoction "

 

the one abstract I found for a more generic unquoted peony and licorice

search yielded this:

 

J Pharmacobiodyn 1983 Mar;6(3):153-60

 

Effect of shakuyaku-kanzoh-toh, a prescription composed of shakuyaku

(Paeoniae Radix) and kanzoh (Glycyrrhizae Radix) on guinea pig ileum.

Maeda T, Shinozuka K, Baba K, Hayashi M, Hayashi E.

The actions of shakuyaku-kanzoh-toh (SK), a prescription of the

traditional Chinese medicine, on an isolated guinea pig ileum were studied

by comparing those of shakuyaku (S) (peony root, Paeoniae Radix) and

kanzoh (K) (licorice root, Glycyrrhizae Radix). SK, S and K suppressed the

neurogenic contractions of ileum induced by electrical stimulation and

ganglionic stimulating agents such as DMPP and nicotine. Although S did

not influence acetylcholine (ACh)-induced contraction of ileum, K

inhibited ACh-induced contraction to the same extent as the neurogenic

contraction. Also SK inhibited ACh-induced contraction but its inhibition

was smaller than the inhibition of the neurogenic contraction. SK and K

inhibited 40 mM KCl-induced contraction of ileum and the specific binding

of 3H-QNB on muscarinic receptors in ileum, but S at 3 X 10(-4) and 10(-3)

g/ml, which were enough to suppress the neurogenic contraction of ileum,

did not inhibit them. These results suggest that the inhibitory actions of

S and K on the neurogenic contraction are due to an inhibition of ACh

release from cholinergic nerve and an inhibition of ACh action on ileum

smooth muscle, respectively, and that the inhibitory actions of SK are

responsible for both inhibitions by S and K. The inhibitions of ACh action

by SK and K are presumed to be due to inhibitions of ACh binding on

muscarinic receptors and of contractile machinery of smooth muscle.

 

So whatever Chen is quoting is not peer reviewed research available on

medline, in which case it may be dubious. this would be especially true

if it is the research of a company that sells such formulas.
