2. • Hallucinogens
• Introduction: Hallucinogens are natural and synthetic
(synthesized) substances that, when ingested (taken into
the body), significantly alter one's state of consciousness.
• Hallucinogenic compounds often cause people to see (or
think they see) random colors, patterns, events, and
objects that do not exist.
• People sometimes have a different perception of time
and space, hold imaginary conversations, believe they
hear music and experience smells, tastes, and other
sensations that are not real.
3. • The other names of hallucinogens are Cartoon acid,
Microdot, California sunshine, Psilocybin, Magic
mushrooms.
• Many types of substances are classified as
hallucinogens, solely because of their capacity to
produce such hallucinations.
• These substances are sometimes called
"pyschedelic," or "mind- expanding" drugs.

7. • Cultivation:
• For sowing the seeds are selected which would
produce strong sturdy plants, rich in leaves is
containing high percentage of alkaloids.
• Seeds are sown in nurseries and seedling is
transplanted deep in well-drained, moist, calcareous
and loamy soil in April.
• Water clogging is harmful to the plants. Addition of
farmyard manure has favourable effect on the growth
of plants weeds are removed.
8. • Tropane alkaloids (0.2-0.5%):
• i. L-hyoscyamine (90%),
• ii. D, L- hyoscyamine(Atropine)
• iii. Scopolamine (10%),
• iv. Apoatropine,
• iv. Belladonnine (+)
9. • Medicinal Uses:
Belladonna can be fatal to most carnivorous
animals and humans, but the same doses have
very little effect upon most birds and plant
eating animals.
Children are often poisoned by the berries,
mistaking them for cherries or other sweet fruit
10. It is used very successfully to treat eye
diseases, because of its effect of dilating the
pupil.
Atropine, an extract of belladonna is what an
eye doctor uses when they put liquid in your
eye before testing you for glasses. Atropine has
also been used as an antidote to opium, calabar
bean, and chloroform poisoning.
Belladonna has been, and is being used as a
recreational drug, diuretic, sedative,
antispasmodic, and mydriatic.
11. In large doses, belladonna acts upon the cerebrospinal
system, as showing such symptoms as:
• dilatation of the pupils (mydriasis),
• presbyopia, (long-sightedness caused by loss of elasticity
of the lens of the eye, occurring typically in middle and
old age) obscurity of vision,
• blindness (amaurosis),
• visual illusions (phantasms),
• suffused eyes (gradually spread through or over)
• occasionally disturbance of hearing (as ringing in the
ears, etc.),
• numbness of the face, confusion of head, giddiness, and
delirium.
