Cannabis sativa
Made from the hemp plant — the fibre and seed of human industry, the chemistry that named the brain's own cannabinoid system, and the classical remedy of the burning urethra.
The whole picture, in one breath
Think of a urinary passage aflame: burning, smarting pain along the urethra after urination, with the sexual excitement and restlessness of the books, and the mind alternating between exaltation and gloom — the hemp plant's classical portrait, recorded before its chemistry changed medicine's map of the brain. The burning-urethra remedy: that is Cannabis sativa.
The substance, in plain words
Hemp is the plant of rope, cloth and seed-oil, its chemistry — the cannabinoids — genuinely among the most consequential of the modern era: the discovery of the brain's own endocannabinoid system transformed neuroscience, and cannabinoid-derived medicines are real, licensed treatments today. The proving gave the remedy the urethral and mental portrait.
The traditional picture Classical sources
The inner state
- Alternation of mood. The keynote of the mind: exaltation alternating with gloom, laughter with tears — the books' noted alternation.
- Anxiety and fear. Fear of death, worse at night; anxiety with the urinary complaints.
- Irritability. Cross, worse from contradiction; the excitable alternation.
The body
- Burning pain after urination. The keynote: smarting, burning pain along the urethra after the stream — the books' great urinary use.
- Sexual excitement with restlessness. The excitement and restlessness of the proving's genital chapter.
- Urinary frequency and urging. The constant urging and frequency accompanying the burn.
- Alternating complaints. The complaints themselves alternate sides and places — the plant's alternation in the body.
- Worse cold damp and night. Wet weather and night deepen the burning.
- Better for rest and warmth. Rest, warmth and quiet ease the passage.

Where it acts (organ affinities)
Urethra and urinary tract, sexual organs, mind and mood.
Where the classical picture comes from
The hemp plant's proving gave the burning-urethra and alternating-mood portrait; Cannabis sativa became the classical remedy of the urinary passage's burn — recorded a century before its chemistry named the brain's own cannabinoid system.
The substance in real medicine Pharmacology
What this section is: the pharmacology and toxicology of the source substance. It is not clinical evidence that a homeopathic preparation of it treats any condition. What controlled trials do and do not show is set out on the Evidence page.
The cannabinoids are genuinely foundational to modern neuroscience: the discovery of the endocannabinoid system — the brain's own cannabis-like signalling — rewrote the map of mood, memory and pain, and cannabinoid-derived medicines are real: CBD treats certain severe epilepsies, and the system remains one of pharmacology's most active frontiers. The burning urethra belongs to modern urology; the chemistry belongs to the century's brain science.
Look-alikes (how the classical authors told it apart)
| Remedy | Looks similar because… | Tells it apart because… |
|---|---|---|
| Cannabis indica | The cannabis pair | Cann indica is the distorted time-and-space and the unquenchable thirst; Cannabis sativa the burning urethra and the alternating mood. |
| Cantharis vesicatoria | Burning urinary states | Cantharis scalds throughout with the urging; Cannabis sativa burns after, with the alternation. |
| Sarsaparilla | End-of-stream pain | Sarsaparilla screams at the final drop; Cannabis sativa burns after, with the mood. |
| Crocus sativus | The alternating moods | Crocus swings with the dark stringy bleeding; Cannabis sativa with the burning and the urinary chapter. |
