Camphene

Camphene is a plant-chemistry name

Camphene is a bicyclic monoterpene found in plant essential oils. When it appears in a cannabis report, the name describes a constituent under that laboratory’s method. It does not identify a medicine or carry a predictable effect with it.

The main study followed a channel and mouse pathway

Researchers tested isolated camphene at Cav3.2 T-type calcium channels, in mouse dorsal-root-ganglion neurons and in mouse models of inflammatory and neuropathic pain. The study recorded changes in channel activity and pain-related behaviour in those models. This is laboratory and animal evidence; no patient used a camphene-containing cannabis product in the experiment.

The handbook entry has a different job

A secondary Marijuana Grower’s Handbook chart is a provenance lead for the name camphene. It is useful for tracing plant-chemistry terminology, but it does not support efficacy, safety or product equivalence. Keeping those jobs separate prevents a chart label from becoming a treatment claim.

A camphene result belongs with the full assay record

The concentration, isomer, batch and complete formulation all remain relevant when a report lists camphene. NHS patient information and the Home Office factsheet provide the prescribed-product and regulatory context. The cited research does not establish clinical pain relief or the effect of a labelled cannabis product, so the camphene line cannot answer those questions.
