I would make an ethanolic extraction (maybe from alcohol of non-gluten source) of the fresh/dried herbs, although I do not have the time to expend/wait, so I just buy it from a mass producer.
The only tinctures I'd prep myself would be fresh cannabis flower (great as a sublingual spray for getting loaded anywhere you can't smoke a joint, plus no heat-mediated toxicity) or some obscure Chinese herbs where my local herbalist is unable to deliver.
Otherwise, let the trials commence...
I wonder why bother with all those tinctures? The stomach responds to bitters before they arrive in it. When bitter flavor touches the tongue, it stimulates the exocrine and endocrine glands. These, in turn, stimulate the digestive juices to the stomach, liver, pancreas and duodenum. The flow of these juices improves the appetite, digestion, and assimilation. The stronger the bitter flavor of the food or herb, the more potent the action.
The digestive juices appear in the intestines within five minutes after a stimulation of the bitter receptors of the tongue and remain there for two or three hours. Why not just put some
bitter herbs under your tongue for 5-10 minutes before and after the meals?
I stll feel a little bit dubious after seeing keto-boy's black shadows/edema...
ZC is not a ketogenic diet just because it excludes the carbs. Mind that most likely NOBODY on this forum is a true ketogenic dieter.
Certain macronutrients may either promote or prevent a ketogenic state, depending whether a given nutrient tend to raise insulin (anti-ketogenic) or glucagon (pro-ketogenic). Here is the ketogenic ratio:
Ketogenic ---
K --- 0.9 fat + 0.46 protein.
Anti-ketogenic ---
AK --- 1.0 carbohydrate + 0.1 fat + 0.58 protein.
This actually means that protein has both ketogenic effects (46%) and anti-ketogenic effects (58%). This reflects the fact that 58% of dietary protein will appear in the bloodstream as glucose, raising insulin and inhibiting ketogenesis. Consequently protein must be restricted to some degree on a ketogenic diet as excessive protein intake will generate too much glucose, impairing or preventing ketosis.
Fat is primarily ketogenic (90%) but also has a slight anti-ketogenic effect (10%). This represents the fact that ten percent of the total fat grams ingested will appear in the bloodstream as glucose (via conversion of the glycerol portion of triglycerides).
For the treatment of epilepsy, the ratio of K to AK must be at least 1.5 for a meal to be considered ketogenic. Typically, this results in a diet containing 4 grams of fat for each gram of protein and carbohydrate, called a 4:1 diet.
This is what Lyle McDonald says about it in "The Ketogenic Diet".
