What this section is, and what it is not
Education and harm reduction. Not medical, legal or financial advice. Every factual claim carries a source; contested and single-source claims are marked as such on the page.
The boundary. This section teaches separation, purification, formulation, dosing arithmetic and analytical chemistry with real parameters, because withholding that detail from someone who will proceed anyway is the harm this library exists to prevent. It does not publish preparative routes for converting one cannabinoid into a more intoxicating one; those are described structurally and cited to the literature, without procedures.
Pages
What a terpene is, how the classes are built from isoprene units, why an essential-oil percentage is not a plant percentage, and what the pharmacology literature actually supports.
6 sections · terpene
The acyclic monoterpene that is usually the dominant terpene in cannabis and in hop oil. Sedative and naloxone-reversible analgesic effects are documented in rodents; the famous blood-brain-barrier claim is not supported in humans.
5 sections · terpene
The bicyclic sesquiterpene with a cyclobutane ring that is a selective CB2 agonist at sub-micromolar concentration — a dietary cannabinoid with GRAS flavouring status. Not a CB1 ligand, contrary to a widespread claim.
8 sections · terpene
The most widely distributed terpene in nature, a bicyclic monoterpene that inhibits acetylcholinesterase in vitro. Dominant in the operator's Helichrysum material at up to 43 percent of the oil.
5 sections · terpene
A monoterpenoid cyclic ether with the best human respiratory trial evidence of any compound on this shelf, and a documented CYP3A substrate relationship. Dominant in Helichrysum odoratissimum at 17.44 percent of the oil.
6 sections · terpene
A cyclic monoterpene — not a biphenyl and not a limonoid, contrary to the operator archive. Monoaminergic anti-stress effects documented in rodents; CYP findings are in-vitro and concentration-limited.
6 sections · terpene
An acyclic monoterpene alcohol with rodent anxiolytic and sedative data, documented effects on glutamate release and on GABA-A receptors — the latter largely via its metabolites rather than the parent compound.
5 sections · terpene
The monocyclic eleven-membered-ring sesquiterpene isomeric with beta-caryophyllene, with genuine rodent anti-inflammatory data in oedema and in allergic airway inflammation — and no cannabinoid receptor activity.
5 sections · terpene
An acyclic monoterpene of the herbivore-induced plant volatile system, dominant in Helichrysum petiolare at 17.21 percent of the oil. Ecologically well characterised, pharmacologically thin.
4 sections · terpene
A thinly documented sesquiterpenoid ketone, reported at 20.66 percent of Helichrysum petiolare oil as a first identification in that species. Almost nothing is known about its pharmacology and this page says so.
4 sections · terpene
A bisabolane-type sesquiterpene hydrocarbon reported at 15.76 percent of Helichrysum odoratissimum oil. Structurally placed, pharmacologically almost undocumented as an isolated compound.
4 sections · terpene
A band-by-band temperature reference from about 140 degrees Celsius to combustion, mapping bands to compound classes, with the caveats that make the numbers usable: set-point is not material temperature, device geometry matters, and terpene loss is progressive and sequential.
