Hahnemann’s proving symptoms of homeopathy remedy Ledum from Materia Medica Pura, which Samuel Hahnemann wrote between 1811 to 1821 …

(Marsh Tea.)

(From vol. iv, 2nd edit., 1825.)

(The twigs of Ledum palustre, quickly dried and powdered, macerated in twenty parts, by weight, of alcohol, to form a tincture.)

The subjoined symptoms, though they are by no means all that might be elicited by proving on the healthy, are yet enough to show that this very powerful medicine is suitable for the most part only for chronic maladies in which there is a predominance of coldness and deficiency of animal heat, particularly as the duration of its action in large doses extends to four weeks.

The dose, in cases of disease for which ledum is homoeopathically adapted. I have found by numerous trials and multiplied experience, requires to be reduced to a small portion of a drop of the quintillionfold attenuation of the tincture.

The evil effects of this medicine when unhomoeopathically selected or given in too large doses, are relieved by frequent smelling of a such solution; but cinchona bark given for the debility produced by ledum is very injurious.

From the following symptoms compared with the similar and identical ill effects of many intoxicating beers, it may be inferred that they are adulterated to a hurtful extent and in a criminal manner with ledum, to which the police authorities should pay more attention.


The old-school authorities quoted are:

LINNAEOUS, Flora Lapponica.

PALLAS, Flora Rossica, tom. I, p. 2.

In the Fragmenta ledum has 80 symptoms, in the 1st edit. 312, and in this 2nd edit. 338.]


When walking and standing vertigo, he could hardly keep himself upright (aft. 9 h.). [Lr.]

Vertigo: the head tends to sink backwards. [Hrr.]

All day long violent vertigo, even when sitting still, which is increased by stooping, and when walking amounts to falling forwards, as if from intoxication, with feeling of heat throughout the body, especially in the face, without thirst, with pale cheeks and forehead (aft. 5 h.). [Lr.]

Stupefaction of the whole head, as in vertigo (aft. ½ h.). [Lr.]

5. Intoxication, giddiness and emptiness in the head.

When walking in the open air he is as if intoxicated. [Fz.]

Incontrollable intoxication. [LINNAEOUS, (Statement.) Flora Lapponica, p. 124.]

Loss of reason. [PALLAS, (Statement. – This was after prolonged intoxication.)Flora Rossica, tom. I, p. ii, p. 94.]

Headache, as from a blow or knock.

10. Head affected; when he makes a false step the brain is painfully shaken.

Headache that makes him feel stupid.

15. Tearing pain in the head and eye; the white and the conjunctiva of the eye are swollen and highly inflamed; the tearing pain in the eye is aggravated by lying and alleviated by sitting; the eyelids are not affected, but in the morning are sealed up as with matter, and an ill smelling moisture exudes from between them; at the same time there is evening rigor, followed by heat, nocturnal thirst, rumbling in the abdomen (with good appetite), more internal than external heat of the head, and sweat on the back and in the hair of the head (aft. 24 h.).

Shooting pain under the right frontal protuberance, in the brain.[Hrr.]

On touching the temple aching pain. (Though no name is attached to this symptom, it occurs among the “observations of others,” and is therefore not one of HAHNEMANN’S observation.)

Aching stupefying pain externally on the forehead, as from dissipation over-night, in every position (Aft. 6 h.). [Lr.]

Crawling itching on the forehead and hairy scalp, as from lice. [Bch.]

25. Pimples and boils on the forehead.

Samuel Hahnemann
Samuel Hahnemann (1755-1843) was the founder of Homoeopathy. He is called the Father of Experimental Pharmacology because he was the first physician to prepare medicines in a specialized way; proving them on healthy human beings, to determine how the medicines acted to cure diseases.

Hahnemann's three major publications chart the development of homeopathy. In the Organon of Medicine, we see the fundamentals laid out. Materia Medica Pura records the exact symptoms of the remedy provings. In his book, The Chronic Diseases, Their Peculiar Nature and Their Homoeopathic Cure, he showed us how natural diseases become chronic in nature when suppressed by improper treatment.
