I can find only 2 Medline abstracts on Chantui-Cicada slough in herbal

medicine:

 

Chem Pharm Bull (Tokyo). 2000 Nov;48(11):1749-52. Optically

active N-acetyldopamine dimer of the crude drug " Zentai, " the cast-off

shell of the Cicada, Cryptotympana sp. Noda N, Kubota S, Miyata Y,

Miyahara K. Faculty of Pharmaceutical Sciences, Setsunan University,

Hirakata, Osaka, Japan. noda Two optically

active N-acetyldopamine dimers together with four phenolic monomers

were isolated from the crude drug " Zentai, " a cast-off shell of the cicada

of Cryptotympana sp. (Cicadidae). The former two were 2-(3',4'-

dihydroxyphenyl)-1,4-benzodioxane derivatives carrying substituents at

the 3 and 6 (or 7) positions, which are known to be components of

sclerotized insect cuticles. Their structures including absolute

configurations were determined on the basis of NMR and circular

dichroism (CD) spectroscopic data. PMID: 11086906 [PubMed -

indexed for MEDLINE]

 

J Ethnopharmacol. 1988 Dec;24(2-3):247-85. Insect-derived crude

drugs in the Chinese Song dynasty. Namba T, Ma YH, Inagaki K.

Research Institute for Waken-Yaku, Toyama Medical Pharmaceutical

University, Japan. Fifty-four kinds of crude drug derived from insects

are listed in the " herbal " Jing-shi-zheng-lei-da-guang-ben-cao (1108

A.D.) edited during the Chinese Song dynasty (960-1280 A.D.). We

considered each of them from the viewpoint of various herbals and have

commented on them, the order being adhered to in most cases. We

added our own findings of identification of insect crude drugs available

on the market. The crude drugs emphasized are mantis egg case,

wasp's nest, scarab larva, red cicada, snipe fly, horse fly, flying

cockroach, Eupolyphaga, Chinese Cantharides and scarab beetle.

Others are discussed to a lesser extent. Publication Types: Historical

Article PMID: 3075674 [PubMed - indexed for MEDLINE]

 

Google has oodles of hits on cicada / chantui but most are commercial

or teaching stuff.
