History of cannabis part I
The marihuana, cannabis, or hemp plant is one of the oldest psychoactive plants known to humanity. It is botanically catalogued as an affiliate of the family Cannabaceae and the genus Cannabis.
Most botanists agree that there are 3 species :
Cannabis sativa, the most far-ranging of the 3, is tall, gangly, and loosely branched, growing as high as 20 feet.
Cannabis indica is shorter, about 3 to 8 feet tall, pyramidal in shape and densely branched ;
Cannabis ruderalis is about 2 feet high with no branches.
There are differences among these species in the leaves, stems, and resin. According to an alternative classification, the genus has only 1 highly variable species, Cannabis sativa, with 2 subspecies, indica and ruderalis. The 1st is more northern and produces more fiber and oil ; the second is more southerly and produces more of the overpowering resin.
Cannabis has changed into one of the most far-reaching and diversified of plants. It grows as weed and cultivated plant all around the globe in a selection of climates and soils. The fiber has been used for fabric and paper for many years and was the most significant source of rope until the development of man-made fibers. The seeds ( or, speaking precisely, akenes – tiny hard fruits ) have been utilized as bird feed and often as human food. The oil contained in the seeds was once used for lighting and soap and is now occasionally employed in the construction of polish, linoleum, and artists’ paints. The chemical compounds accountable for the stimulating and medical effects are found principally in a sticky golden resin discharged from the flowers on the female plants. The function of the resin is assumed to be protection from heat and preservation of moisture during reproduction. The plants highest in resin so grow in hot regions like Mexico, the Middle East, and India.
When the reproductive process is over and the fruits are fully ripe, no more resin is secreted.
The cannabis preparations used in India frequently function as a people standard of virility. The 3 types are referred to as bhang, ganja, and charas. The least strong and most cost-effective preparation, bhang, is produced from the dried and crushed leaves, seeds, and stems. Ganja, prepared from the blossoming tops of cultivated female plants, is 2 or 3 times as powerful as bhang ; the difference is rather similar to the difference between lager and fine Scotch. Charas is the pure resin, a. K. A hashish in the Middle East.
Any of these preparations can be smoked, eaten, or mixed in drinks. The marihuana used in the U. S. is equal to bhang or, increasingly in recent times, to ganja. The marihuana plant contains more than 460 known compounds, of which more than 60 have the 21-carbon structure characteristic of cannabinoids. The sole cannabinoid that’s both highly psychoactive and present in big amounts, customarily 1-5 p.c by weight, is ( – ) 3,4-trans-delta-l- tetrahydrocannabinol, sometimes called delta-1-THC, delta-9-THC, or just THC. Some other tetrahydrocannabinols are roughly as potent as delta-9-THC but present in some sorts of cannabis and in much littler quantities.
A number of man-made congeners of THC have been developed under such names as synhexyl, nabilone, and levonatradol. The other 2 major sorts of cannabinoid are the cannabidiols and the cannabinols. It would appear the plant first produces the softly active cannabidiols, which are converted to tetrahydrocannabinols and then damaged down to comparatively inactive cannabinols as the plant matures. The up to date discovery of nerve receptors in the brain excited by THC ( and the cloning of the gene that leads to these receptors ) implies that the body produces its own version of the substance. The receptors are found typically in the cerebral cortex, which rules higher thinking and in the hippocampus, which is a locus of memory. A local of central East Asia, cannabis could have been cultivated so long as 10 thousand years back. It was definitely cultivated in China by four thousand B.C. And in Turkestan by 3k B.C.
It has always been used as a drugs in India, China, the Middle East, Southeast Pacific Rim, S. A. , and South America. The 1st proof for medical use of cannabis is an herbal revealed during the reign of the Chinese emperor Chen Nung 5,000 years back.
Cannabis was suggested for malaria, hard stools, rheumatic pains, dreaminess, and female aberrations. Another Chinese herbal suggested a mix of hemp, resin, and wine as a drug in surgery. In India cannabis has been advised to speed up the mind, lower fevers, prompt sleep, cure dysentery, excite appetite, improve digestion, relieve headaches, and cure venereal illness. In Africa it was employed for dysentery, malaria, and other fevers. Today certain clans treat snake bites with hemp or smoke it before childbirth. Hemp was also noted as a cure by Galen and other doctors of the classical and Hellenistic ages, which was highly valued in medieval Europe. The English priest Robert Burton, in his famous work The Anatomy of Melancholy, published in 1621, advised the utilization of cannabis in the handling of depression.
