Crystal healing is a pseudoscientific alternative-medicine practice that uses semiprecious stones and crystals such as quartz, agate, amethyst or opal. Despite the common use of the term "crystal", many popular stones used in crystal healing, such as obsidian, are not technically crystals .
3-Methylmethcathinone (3-MMC), also known as metaphedrone, [4] is a designer drug from the substituted cathinone family. 3-MMC is a monoamine transporter substrate (a substance acted upon by monoamine transporters) that potently releases and inhibits the reuptake of dopamine and norepinephrine, as well as displaying moderate serotonin releasing activity.
The primary psychological effects have a duration of roughly 3 to 4 hours, with aftereffects such as tachycardia, hypertension, and mild stimulation lasting from 6 to 8 hours. [13] High doses have been observed to cause intense, prolonged panic attacks in stimulant-intolerant users, [ 13 ] and there are anecdotal reports of psychosis from sleep ...
The effects are likely comparable to those of other cathinones of which it is known exposure can result in symptoms such as tachycardia, hypertension, and episodes of psychosis. [2] Users also report other side effects including an increase in body temperature, sweating , anxiety , and dry mouth .
Pyromorphite is a mineral species composed of lead chlorophosphate: Pb 5 (P O 4) 3 Cl, sometimes occurring in sufficient abundance to be mined as an ore of lead. [5] Crystals are common, and have the form of a hexagonal prism terminated by the basal planes, sometimes combined with narrow faces of a hexagonal pyramid. [6]
β-Carotene (beta-carotene) is an organic, strongly colored red-orange pigment abundant in fungi, [7] plants, and fruits. It is a member of the carotenes, which are terpenoids (isoprenoids), synthesized biochemically from eight isoprene units and thus having 40 carbons.
Its chemical structure closely resembles para-chloromethamphetamine, raising concerns about its potential to readily induce cell death of serotoninergic neurons.However, no neurotoxicity of this kind has been found, but studies involving mice do indicate that it is neurotoxic through other mechanisms. 4-CMC is cytotoxic and induces oxidative stress.
It became popular in the late 18th century to give calomel in extremely high doses, as Benjamin Rush normalized the heroic dose. This caused many patients to experience many painful and sometimes life-threatening side effects. Calomel, in high doses, led to mercury poisoning, which had the potential to cause permanent deformities and even death.
