Interesting though. Although I already read these through other various sources.
The medical dose for atropine, as I have read in pharmaceutical literature, starts at 500 ug up to 2 mg, generally 1 mg. Often used to assure a safe heart pulse for a patient that's getting a narcosis for an upcoming operation.
Also, effects such as blindness, pressure on the eyes, hot and red skin, fever, severe dehydration, difficulty in urination, weakness, losing ability to sweat, increased or decreased heart pulse and hallucinations are typically linked to a dose in the 4-6 mg range. Expandend stomach does occur. So does amnesia.
Anything over 6 or around 10 mg's, results in all of the effects above as well as a paralyzed body, extreme difficulty in breath, swollen tongue so bad that one can't swallow or even talk, expanded stomach and veins so bad that it feels like there's something about to explode in one's body. Unconsciousness and deep coma.
The effects on the psyche are not well documentated at such an OD, but it is assumed that the patient has lost connection with his actual presence, and has truly gotten a life in a dream world only known by his soul, experienced as reality. There are beliefs of flying through the air to anyplace, anywhere, anytime. But stories are so vague that no one knows for sure, except of course those very few. Yet often speaking with a marvellous passion to be noticed as charming.
Even under medical supervision it is known to be dangerous to practice unconsciousness states with critical safety precautions. But I believe it has these doors, but it is worth the risk to perform such a practice which even strikes fear amoung those who have studied toxicology extensively?
Anyway, alkaloid balance seems essential. From a phamaceutical point of view, recreational users of solanaceae's are combining 3 powerful alkaloids at once with perhaps only a general indication of the dose, or no indication at all. Often eye-ball dosages are done of what they think is right. Note that delirium can already occur from half a teaspoon or less than one cherry of the atropa belladonna. Who is famous for her potency of atropine and she can hold 2 mg's of atropine in each cherry if she's really potent.
Scopolamine and Hyoscamine are the two other major alkaloids. Better to do an eloborated search on these as well since it distinguishes slightely in effects. Solanaceae's do have a weird power since they sedate muscles except for the heart which is getting frequent strong contractions, which can be potentially dangerous.
Additional psychoactives, such as alcohol, coffee, opium and herbs which fight the anticholinergenic effects are added to brews to induce relaxtion, ability to urinate and to treat anxiety or panic which helps to have a experience of which someone is more aware. Although I doubt that it's practiced properly nowadays. Only on a very minor scales within some tribes maybe.
Sexual arousal has always been linked to the solanaceae's, possibility the heighted temprature of the skin and the wild vivid dreams, along with the additions in the brews of witchcraft might have contributed to that power.
It is weird that Ibogaine is too 'controversial' while solanaceae's are simply seen as just a plant. In my opinion, the use of tropanes is the most dangerous path one can go into, it requires very low dosages and a cardiac failure is real. Not even to mention the complex flashing effects in where one has no idea how he got into it, or whether it is real or not.
Elaborated hallucinations and prolonged interactions with them seems to be unique, and an experience which can be never acquired through the use of LSD.
But on the other hand, LSD has left heavenly spores within our world due to the teachings it has given millions of minds. It speaks to one in public, but also has a side which guarantees a person's individual strength.
The solanaceae's never managed it to pass on a notorious message to the world through teaching the human mind. Her power is a closed hand in order to secude one's subconsciousness, she only shows what she has if the participant has gotten himself locked into her house. Within the earth that is.
A man is flying within himselve if he dared to try out a path which other men haven't, it makes him feel he's closer to there where his normal percepted existance tells him to be. Datura is very well aware of this typical aspect of manhood. Taking life and giving life.
The man who acts as wild as an animal, with a gravity stone around his neck, might be adored and worshipped by his fellow sufferers. But it makes no sense to a man who has rised himself to states of awareness in where gravity is unknown.
If life could be for eternity with just it's content and no emotions attached to it, I'd reject it without a doubt. The fear that once your existance with feelings stops for evermore, is an agreed peace to me.
