Medicinal Uses
Datura has long been used as an extremely effective treatment for asthma symptoms. The active anti-asthmatic agent is atropine, which causes paralysis of the pulmonary branches of the lungs, eliminating the spasms that cause the asthma attacks. The leaves are generally smoked either in a cigarette or a pipe. This practice of smoking datura to relieve asthma has its origins in traditional Ayurvedic medicine in India. After this was discovered during the late 18th century by James Anderson, the English Physician-General of the East India Company, the practice quickly became popular in Europe.
The Zuni used to use datura as an analgesic, to render patients unconscious while broken bones were set. The Chinese also used it in this manner, as a form of anaesthesia during surgery.
Atropine and scopalamine (both of which are found in very high concentrations in datura) are muscarinic antagonists which can be used to treat Parkinson's disease and motion sickness, and to inhibit parasympathetic stimulation of the urinary tract, respiratory tract, GI tract, heart and eye.
Datura can be used to assist in the process of breaking drug addictions, by reducing the symptoms of delirium tremens and morphine withdrawals.
Other medicinal uses for datura include providing relief from sore throat or toothache and getting rid of parasites.
Datura should be avoided by patients with heart problems, glaucoma, enlarged prostate, urinary difficulties, fluid buildup in the lungs, or bowel obstructions.

“by Spoon Rivergathering many a shell,
And many a flower and medicinal weed
Shouting to the wooded hills, singing to the green valleys.
At ninety-six I had lived enough, that is all,
And passed to a sweet repose.”
