The electrical activity you are measuring reflects both the intrinsic activity of neurons in the cerebral cortex and the information sent to it by subcortical structures and the sense receptors. This composite activity is called an electroencephalogram or EEG.
Now letâs be clear, your fresh plant tincture WONâT be 95% alcohol because the fresh plant itself contains water (how much depends on the plant of course), so itâs not quite like taking a dropperful of Everclear or something. Some plants have tons of water in them (think of juicy plants like Plantain or Wild Mint). And hey, if you want to only use 50% alcohol for your tincture, well then hell, just use half water and half grain alcohol. For dry plant tinctures, youâll rarely use 95% alcohol but it makes it really easy to calculate the exact percentage that you do need. So if you need 45% alcohol for your dried Ashwagandha, why then just add enough water to the alcohol to make that (again, appr. half and half, I personally usually just eyeball it).
Researchers injected ethyl alcohol into 16 tarsometatarsal joints (lowest hock joint) of normal, sound horses. They injected 4 mL of either 70% or 95% ethyl alcohol. Horses had minimal or no lameness following the injections.
