Ergine, also known as d-lysergic acid amide (LSA) and d-lysergamide, is an
Occurrence in nature
Ergine has been found in high concentrations of 20 μg/g dry weight in the
Ergine is a component of the alkaloids contained in the ergot fungus, which grows on the heads of infected rye grasses.
It is also found in the seeds of several varieties of
History
Ololiuhqui was used by South American healers in shamanic healing ceremonies.[10] Similarly, ingestion of morning glory seeds by Mazatec tribes to "commune with their gods" was reported by Richard Schultes in 1941 and is still practiced today.[11][10]
Sewell RA. Entheogen Rev. 2008;16:117-25.
Additional reports of the use of ergine were made by Don Thomes MacDougall. He reported that the seeds of
Ergine was assayed for human activity by
In 1956, the
In 1959, Hofmann was the first to isolate chemically pure ergine from the seeds of
Ingestion
Like other psychedelics, ergine is not considered to be addictive. Additionally, there are no known
Physiological effects
While its physiological effects vary from person to person, the following symptoms have been attributed to the consumption of ergine or ergine containing seeds:[7][10][16]
- Sedation
- Visual and auditory hallucinations
- Euphoria
- Loss of motor control
- Nausea
- Vasoconstriction
- Delusion
- Anxiety
- Paranoia
- Irregular heartbeat[17]
- Sexual arousal[18]
- Tachycardia[19]
- Mydriasis[19]
- Hypertonia[19]
- Respiratory disturbances[19]
- Cramps[19]
One study found that 2 of 4 human subjects experienced cardiovascular dysregulation and the study had to be halted, concluding that the ingestion of seeds containing ergine was less safe then commonly believed. Importantly this may have been a product of other substances within the seeds. The same study also observed that reactions were highly differing in type and intensity between different subjects.[17] Another study in mice found that the drug had aphrodisiac properties, inducing increased sexual behavior.[18]
A study gave mice 3000 mg/kg with no lethal effects.[citation needed]
Psychedelic component
Ergine is thought to be a
The idea that ergine is the main psychedelic component in ergine containing seeds (morning glory, Hawaiian baby woodrose) is well debated, as the effects of isolated synthetic ergine are reported to be only mildly psychedelic.[9][16] Thus, the overall psychedelic experience after consumption of such seeds has been proposed to be due to a mixture of ergoline alkaloids.

Chemistry
Biosynthesis
The biosynthetic pathway to ergine starts like most other ergoline alkaloid- with the formation of the ergoline scaffold. This synthesis starts with the
From here, the biosynthesis diverges and the products formed are plant and fungus-specific. The biosynthesis of ergine in
Legal status
The legality of consuming, cultivating, and possessing ergine varies depending on the country.
There are no laws against possession of ergine-containing seeds in the United States. However, possession of the pure compound without a prescription or a DEA license would be prosecuted, as ergine, under the name "lysergic acid amide", is listed under Schedule III of the Controlled Substances Act.[24] Similarly, ergine is considered a Class A substance in the United Kingdom, categorized as a precursor to LSD.
In most Australian states, the consumption of ergine containing materials is prohibited under state legislation.
In Canada, ergine is not illegal to possess as it is not listed under Canada's Controlled Drugs and Substances Act, though it is likely illegal to sell for human consumption.[25]
In New Zealand, ergine is a controlled drug, however the plants and seeds of the morning glory species are legal to possess, cultivate, buy, and distribute.
