Tincture Time

Just the aerial parts now they're all done.  A remarkably 'medicinal' fragrance, almost like an antiseptic when I was cutting them up.  The main volatiles in the flower heads seem to be β-myrcene, α-pinene, limonene, camphene, β-pinene; all of which have anti-microbial activity and there is also camphene, and terpinene, the more 'antiseptic' smell, I suspect.
Echinacea also contains dimethyl sulphide, which smells like cabbages, but I couldn't detect that.
In my high alcohol, cold extraction, should get all the higher active volatiles, and hopefully less DMS.
