Nature's Herbarium Pharmacopeia: Strange Psychedelic Plants

Alex Coppen -

Mother Nature's pantry is bursting with electrochemical wonder. Thousands of psychedelic plants have been catalogued by chemists and botanists. As miniature laboratories, they produce molecules of such staggering complexity, its often hard to believe your eyes.

It can be hard to find a reference source or encyclopaedia index where you can start on your exploration if you are a chemist. But you soon discover why a large degree of scientists are fascinated by the planet's natural medicine cabinet.

Microscopic Artistry Few Ever See

There are days when you look at the structure of molecules and think God is showing off. Until you realise nobody ever really gets to see them. There is a mathematical beauty in the chemical world which is simply breathtaking.

The compound Ibogaine, found in the root bark of Tabernanthe iboga is a substituted tryptamine with the reported ability to break addiction to opiates and opoids. Its structure is wondrous.

(1R,15R,17S,18S)-17-ethyl-7-methoxy-3,13-diazapentacyclo[13.3.1.02,10.04,9.013,18]nonadeca-2(10),4(9),5,7-tetraene

Cocaine, a benzoate ester tropane alkaloid from Erythroxylum coca is where all our dental anaesthetics are derived from. Few have ever tried to reproduce it in a laboratory because of its sophisticated structure.

Why Do They Exist At All?

The greatest mystery is why, perhaps, there are plants which have psychedelic effects on us. Why do we have receptors for them to bind to?

Much can be traced back to the shared evolutionary history of plants and animals, as well as the similarities in the basic biochemistry of living organisms. Many of the receptors and neurotransmitter systems in the human brain have evolved from ancient molecular pathways that are present in simpler organisms, including plants. As a result, some compounds produced by plants can interact with these receptors due to their structural similarity to endogenous neurotransmitters or signaling molecules.

Plants and animals have co-evolved over millions of years, and some plants may have developed compounds that interact with animal neurotransmitter systems as a defense mechanism against herbivory or to encourage the dispersal of their seeds by animals. In turn, animals have evolved receptors that respond to these compounds.

Some plant compounds are structurally similar to endogenous neurotransmitters or signaling molecules in the human brain (i.e. ones we naturally produce in our bodies already). These compounds can bind to and activate or inhibit the same receptors that respond to the endogenous molecules, resulting in psychoactive effects. For example, the psychoactive compound in marijuana, THC, binds to the brain's endocannabinoid receptors (CB1 and CB2), which normally respond to naturally occurring cannabinoids in the body.

Some plant compounds may not directly bind to receptors in the brain but instead modulate (i.e. make stronger or weaker) the activity of endogenous neurotransmitter systems. For example, some compounds may inhibit the breakdown or reuptake of neurotransmitters, leading to increased levels of these molecules in the brain and altered neural activity.

Grouping The Pantry's Shelves

Psychoactive compounds can broadly be categorised into ten different groups, based on their molecular structure. Often these are used as "backbone" templates for new molecules.

The Ephedra genus, for example, found all over the world, produces the phenethylamine alkaloid Ephedrine ((1R,2S)-2-(methylamino)-1-phenylpropan-1-ol). When reduced, the result is 4-methyl-amphetamine; when oxidated, the result is methcathinone. If we continue to methylate the latter, the result is Mephedrone (4-methyl-methcathinone). As such, Ephedrine is the natural template for amphetamines.

  1. Tryptamines: derived from tryptamine, often with psychedelic effects (e.g., DMT, Psilocybin, Psilocin, 5-MeO-DMT, Bufotenin)
  2. Phenethylamines: a phenethylamine core structure, including stimulants and psychedelics (e.g., Mescaline, MDMA, Amphetamine, Cathinone)
  3. Benzofurans: a benzofuran ring, often with entactogenic effects (e.g., 5-APB, 6-APB, 5-MAPB)
  4. Lysergamides: derived from lysergic acid, known for their potent psychedelic effects (e.g., LSD, LSA, ETH-LAD)
  5. Beta-carbolines: a beta-carboline structure, often with MAO-inhibiting and mild psychedelic effects (e.g., Harmine, Harmaline, Tetrahydroharmine)
  6. Piperazines: a piperazine ring, often with stimulant or entactogenic effects (e.g., BZP, mCPP, TFMPP)
  7. Cannabinoids: found in cannabis or synthetic analogues, known for their varied effects (e.g., THC, CBD, CBN, JWH-018)
  8. Opioids: act on opioid receptors, known for their pain-relieving and euphoric effects (e.g., Morphine, Codeine, Thebaine, Kratom alkaloids)
  9. Dissociatives: causing dissociative effects, often acting as NMDA receptor antagonists (e.g., Ketamine, PCP, DXM, Salvinorin A)
  10. Xanthines: a xanthine core structure, known for their stimulant effects (e.g., Caffeine, Theobromine, Theophylline)

Strange Effects In Humans

Although most plants produce many different compounds simultaneously, we can also broadly group their activity by their strongest and most pronounced effects. Cannabis sativa, for example, contains over 100 cannabinoids; only three are used recreationally. Two cannabinoids are found naturally in the human body ("endo"): anandamide, or AEA, and 2-arachidonoyl glycerol, known as 2-AG.

Hallucinogens/Psychedelics

Many psychedelic compounds, such as psilocybin, DMT, and mescaline, bind to and activate serotonin receptors, particularly the 5-HT2A receptor subtype. Activation of these receptors leads to increased excitatory neurotransmission and altered perception, mood, and cognition. Some psychedelics, like ibogaine, may also interact with other neurotransmitter systems, such as the dopaminergic and glutamatergic systems.

  • Cannabis (THC)
  • Psilocybin Mushrooms (Psilocybin, Psilocin)
  • Peyote (Mescaline)
  • Ayahuasca (DMT, Harmine, Harmaline)
  • Salvia (Salvinorin A)
  • Morning Glory (Ergine)
  • Hawaiian Baby Woodrose (Ergine)
  • Iboga (Ibogaine)
  • Yopo (Bufotenin, DMT)
  • Acacia (DMT, Mescaline)
  • Chacruna (DMT)
  • Chaliponga (DMT, 5-MeO-DMT)

Stimulants

Stimulant compounds typically interact with the dopamine and norepinephrine neurotransmitter systems. Compounds like cocaine and cathinone inhibit the reuptake of dopamine and norepinephrine, leading to increased levels of these neurotransmitters in the synaptic cleft and enhanced neurotransmission. Other stimulants, such as caffeine, act as adenosine receptor antagonists, promoting wakefulness and alertness.

  • Tobacco (Nicotine)
  • Coca (Cocaine)
  • Khat (Cathinone, Cathine)
  • Ephedra (Ephedrine, Pseudoephedrine)
  • Guarana (Caffeine)
  • Yohimbe (Yohimbine)
  • Betel Nut (Arecoline)
  • Guayusa (Caffeine, Theobromine)
  • Cacao (Theobromine, Caffeine)

Sedatives/Depressants

Sedative compounds often interact with the gamma-aminobutyric acid (GABA) neurotransmitter system, which is the primary inhibitory neurotransmitter in the brain. Compounds like kavalactones and valerenic acid may enhance the effects of GABA by binding to GABA receptors or modulating the activity of GABA-producing enzymes, leading to increased inhibitory neurotransmission and feelings of relaxation and sedation. Opioid compounds, such as morphine and codeine, bind to opioid receptors in the brain, leading to reduced pain perception and feelings of euphoria.

  • Opium Poppy (Morphine, Codeine)
  • Kratom (Mitragynine, 7-Hydroxymitragynine)
  • Kava (Kavalactones)
  • Valerian (Valerenic acid, Isovaleric acid)
  • Passionflower (Harman alkaloids)
  • Catnip (Nepetalactone)
  • Hops (Humulone, Lupulone)

Anxiolytics

Anxiolytic compounds typically interact with the GABA neurotransmitter system, similar to sedatives. These compounds may enhance the effects of GABA, leading to reduced anxiety and increased relaxation. Some anxiolytic compounds, like baicalin and baicalein, may also interact with serotonin receptors, modulating serotonergic neurotransmission.

  • Kava (Kavalactones)
  • Passionflower (Harman alkaloids)
  • Ashwagandha (Withanolides)
  • Lemon Balm (Rosmarinic acid, Linalool)
  • Skullcap (Baicalin, Baicalein)

Antidepressants

Antidepressant compounds often interact with the serotonin, norepinephrine, and dopamine neurotransmitter systems. Compounds like hypericin and hyperforin (found in St. John's Wort) may inhibit the reuptake of these neurotransmitters, leading to increased levels in the synaptic cleft and enhanced neurotransmission. Other compounds, such as 5-HTP (found in Griffonia), serve as precursors to serotonin, increasing its production in the brain.

  • St. John's Wort (Hypericin, Hyperforin)
  • Saffron (Crocin, Safranal)
  • Griffonia (5-HTP)

Cognitive Enhancers/Nootropics

Cognitive enhancers and nootropics can have diverse mechanisms of action, targeting various neurotransmitter systems and brain pathways. Some compounds, like ginkgolides and bilobalide (found in Ginkgo biloba), may improve cerebral blood flow and protect against oxidative stress, supporting cognitive function. Others, such as bacosides (found in Bacopa monnieri), may modulate cholinergic and serotonergic neurotransmission, enhancing memory and learning.

  • Ginkgo (Ginkgolides, Bilobalide)
  • Bacopa monnieri (Bacoside A, Bacoside B)
  • Gotu Kola (Asiaticoside, Madecassoside)
  • Ashwagandha (Withanolides)
  • Rhodiola rosea (Salidroside, Rosavin)
  • Lion's Mane Mushroom (Hericenones, Erinacines)

Adaptogens

Adaptogens are believed to help the body adapt to stress by modulating the hypothalamic-pituitary-adrenal (HPA) axis and other stress-response systems. Compounds like withanolides (found in Ashwagandha) and salidroside (found in Rhodiola rosea) may interact with the HPA axis, reducing cortisol levels and promoting a balanced stress response. Adaptogens may also have neuroprotective and anti-inflammatory effects, supporting overall brain health and resilience.

  • Ashwagandha (Withanolides)
  • Rhodiola rosea (Salidroside, Rosavin)
  • Ginseng (Ginsenosides)
  • Holy Basil (Eugenol, Ursolic acid)
  • Eleuthero (Eleutherosides)
