Pour réussir à mettre au point leur traitement contre le palu, les chercheurs chinois avaient mis en évidence qu'il ne fallait pas faire de tisanes, mais extraire le principe à froid.
Et ça, c'était il y a plus de 50 ans.

![“….In Ge Hong’s A Handbook of Prescriptions for Emergencies, I noticed one
sentence “A handful of Qinghao (herbs of Artemisia family) immersed in two liters of
water, wring out the juice and drink it all”, when Qinghao was mentioned for
alleviating malaria fevers. Most herbs were typically boiled in water and made into a
decoction before taken by the patients [*decoction, method of extraction by
boiling herbal or plant material to dissolve the plant chemicals, which may include first
mashing the plant material for maximum dissolution, and then boiling in water
to extract oils, volatile organic compounds and other chemical substances]. This
unique way of using Qinghao gave me the idea that heating during extraction might
have destroyed the active components and the high temperature might need to be
avoided in order to preserve the herb’s activity. Ge Hong’s handbook also mentioned
“wring out the juice.” [meaning * to squeeze or twist especially so as to make dry or to
extract moisture or liquid]. This reminded me that the leaf of Qinghao might be one of
the main components prescribed. I redesigned experiments in which the stems and
leaves of Qinghao were extracted separately at a reduced temperature using water,
ethanol and ethyl ether…..”.](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:w477bdrwbpo2u4ra3aq33pki/bafkreiexhvtzzajak2zzs6ttfrqqnvjtjgkdgqi4jkekk7zaacwojrsykm@jpeg)
