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).
Alcohol Abuse Doesnât Just Mean More Cavities. Pure alcohol on its own will not damage oneâs teeth. However, most people donât drink pure alcohol. Beer, liquor and mixed drinks have high sugar content and high acidity, breaking down the enamel that protects your teeth. This can lead to cavities, long term tooth decay and increase the risk of periodontal disease. People that suffer from alcohol abuse may also forget to brush their teeth. While once in a while forgetting to brush isnât the end of the world, poor dental hygiene can have long-term repercussions.
