sealed glass tube with asian writing and brown powder

三蛇胆 ( 蛇胆 is like the bile of the snake? )is the main reason why the thing is sealed in glass. in a western sense it prevents like air from entering the medicine and causing oxidation and making the medicine go bad.

to unseal it all you do is to break the glass, maybe in newspaper to protect from glass shards. the reason to use glass probably stems from its simplicity in solving the problem of preserving the medicine so that it doesnt potentially turn bad. other materials wont work as well as glass

the medicine cures cough and digestive related issues i believe, coupled with the tangerine peels

source, im asian, and this (translate it using google translate) chinese website
