Coffea cruda
Made from raw coffee — the unroasted bean of the world's favourite stimulant, and the classical picture of a mind that will not switch off.
The whole picture, in one breath
Think of a mind over-lit: sleepless from sheer excitement — good news, new ideas, an argument replayed — senses sharpened to pain, hearing acute, thoughts racing faster than sleep can catch. Sleeplessness from excitement, acute senses, racing thoughts: that is Coffea cruda.
The substance, in plain words
Coffee is the seed of a red-berried tree, and its stimulant is caffeine — the most widely consumed psychoactive substance on earth. The homeopathic picture is drawn not from poisoning but from the ordinary over-stimulation everyone knows: one cup too many, after midnight.
The traditional picture Classical sources
The inner state
- Sleeplessness from excitement. The keynote: cannot sleep from an over-joyful or over-active mind — plans, ideas, the day's events replayed at speed.
- Over-acute senses. Hearing, smell and touch unbearably sharp; the slightest noise jars; pain felt more than it should be.
- Racing, fidgeting thought. One idea chases another; fidgets, talks fast, laughs easily, weeps at music.
The body
- Wired but tired. Sleepless yet not sleepy — the exhausted body carried by a spinning mind.
- Headaches of over-stimulation. Aching, bursting headache as if the brain were too tight, worse for noise and thinking.
- Palpitations with excitement. Heart fluttering after joy, coffee or surprise; trembling of the hands.
- Toothache made sharp. Pains intolerable — 'pains are unbearable' is the quoted phrase of the proving.
- Worse for coffee. The substance aggravates its own picture — coffee after dinner, no sleep.
- Better for warmth and quiet. Warmth, darkness and stillness gradually let the senses settle.

Where the classical picture comes from
The proving with raw coffee produced the classic caffeine state — excitation, acute senses, sleeplessness — and the remedy was then applied to the same state arising from any cause: joy, grief, overwork of the brain.
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.
Caffeine is genuine, dose-dependent pharmacology: a stimulant that blocks adenosine receptors, sharpening attention at one dose and wrecking sleep at another. Modern sleep medicine manages exactly the state Coffea portrays — with sleep hygiene, and an honest look at the last coffee of the day.
Look-alikes (how the classical authors told it apart)
| Remedy | Looks similar because… | Tells it apart because… |
|---|---|---|
| Nux vomica | Irritability, stimulant effects | Nux is cross, chilly and digestive; Coffea is excited, acute and sleepless from joy. |
| Ignatia amara | Emotional sleeplessness | Ignatia is grief with sighs and sobbing; Coffea is excitement with racing ideas. |
| Aconitum napellus | Restlessness, fear | Aconite is terror of death after shock; Coffea is pleasant overstimulation that will not end. |
| Kali phosphoricum | Mental exhaustion | Kali-phos is drained and grey after overwork; Coffea is over-charged and bright. |
