LSD

From my experience LSD is a substance for self-healing. Many ailments physical and in the mind can be healed by LSD experiences, even without guidance.

“It is perhaps no coincidence but of deeper biological significance that of the four possible isomers of LSD, only one, which corresponds to natural lysergic acid, causes pronounced mental effects. Evidently, the mental functions of the human organism, like its bodily functions, are particularly sensitive to those substances which possess the same configuration as naturally occurring compounds of the vegetable kingdom.” – Albert Hofmann

LSD is a very curious chemical. When given by injection, it disappears rapidly from the blood. It can be observed when tagged with Carbon 12 in all the tissues, particularly the liver, spleen, kidneys and adrenal glands. The concentration found in the brain is lower than in any other organ — being only about 0.01 percent of the administered dose. Sidney Cohen, in The beyond Within (p. 380), has estimated that an average dose results in only some 3,700,000 molecules of LSD (about 2/100ths of a microgram) crossing the blood-brain barrier to interact with the billions of cells that make up the average-size brain — “and then for only a very few minutes”.

LSD deteriorates slowly over time, oxidizing into iso-LSD. In about a decade, potency decreases by half. Some writers have exaggerated the deterioration involved. It does, however, disintegrate rapidly in the presence of light, oxygen and moisture – Peter Stafford – The Psychedelic Encyclopedia
