Caffeinum

1,3,7-Trimethylxanthine; 1,3,7-trimethylpurine-2,6-dione. Appears in older homeopathic literature as Coffeinum / Coffein / Caffein. · Caffeine; Coffein; Caffein; the alkaloid of coffee and tea

Modern MM

A nervous- and vascular-system stimulant remedy. Its sphere centres on cerebral and arterial excitation — throbbing, sleeplessness and over-stimulation of mind and circulation — closely paralleling, and largely subsumed within, the picture of Coffea cruda.

Key symptoms

Marked pulsation/throbbing of the arteries of the head and temples; sparks before the eyes with roaring in the ears; violent palpitation with very rapid, irregular, often intermittent pulse; restlessness, dizziness and inability to keep erect; violent precordial anxiety with trembling of the extremities; great excitement of the nervous and vascular systems with inability to fix the mind; vomiting followed by relief of all symptoms. (Clarke; Allen, Encyclopedia of Pure Materia Medica.)

Worse (aggravation)

Sourced modalities are sparse. Clarke and Allen note vomiting was followed by relief of all symptoms. No reliable, broadly attested aggravating modalities are recorded for the isolated alkaloid beyond those of Coffea.

Better (amelioration)

Amelioration after vomiting (relief of all symptoms following emesis, after about one hour), per Clarke and Allen. Otherwise see Coffea.

Caffeine; Coffein; Caffein; the alkaloid of coffee and tea

Source & Nature

Caffeinum is the homeopathic preparation of caffeine, the purine (methylxanthine) alkaloid of coffee and tea, obtained from Coffea arabica (C8H10N4O2; CAS 58-08-2; PubChem CID 2519). In the classical homeopathic literature it appears under the Latin name Coffeinum (Clarke; Allen). Pharmacologically caffeine is a central-nervous-system and cardiovascular stimulant acting as an adenosine-receptor antagonist.

Preparation

Made by trituration of the pure alkaloid; the citrate salt (Citrate of Coffein) is also referenced in the older provings. Commercially available from homeopathic pharmacies as Caffeinum in potencies 6C, 30C, 200C, 1M and higher.
