Comment:
Asarum is an important medicine in both East and West. The Chinese variety and uses are compatible with the Western variety and its uses, and the Chinese variety was known and used in the West synonymously (see History below). Its actions derive from its hot, piercing and pungent qualities which penetrate through obstructions, open the capillaries and skin pores to resolve obstructions of Wind, Cold, Damp, Phlegm and Blood.
It is very useful for acute Wind-Cold Cold and Flu with nasal congestion, feeling of cold, cough with watery sputum and headache. It is also an important ingredient in formulas to clear Cold and Damp from the muscles and joints. In the West it was an important ingredient in a number of formulas used for ‘Obstruction’, usually a mixture of Phlegm, Damp with Qi and Blood Stagnation.

Cautions:
1. Toxic in overdose. Avoid long-term use. It is a member of the Aristolchia family; some species contain high levels of safrole.

3. Not used in Yin deficiency (dryness)
4. In TCM, Asarum is considered antagonistic to Cornus Shan Zhu Yu and Astragalus. It is incompatible with Veratrum nirgum and counters the effect of Talcum.
Toxicity:
The herb is toxic and is banned in many countries due to its Safrole and Aristolchic acid content
–Long-term oral administration of Asarum heterotropoides f. mandshuricum (Maxim.) Kitag. decoction and its aristolochic acid analogs do not cause renal toxicity in mice.
–Evaluating the toxicity of the roots of Asarum heterotropoides var. mandshuricum extracted using the decoction method: Genotoxicity, single-dose toxicity, and 13-week repeated-dose toxicity studies.
Main Preparations used:
Galen:
“Its useful part is the root, and its strength is like that of sweet flag (Acorus), even stronger”.
Dioscorides:
“It is called wild-nard; its leaves resemble ivy-leaves, but are smaller and more round. Its flowers, situated between the leaves near the root, are purple-coloured and resemble the flowers of the henbane (Hyoscyamus ). Its seeds are like those of the cartham. It has many roots bearing thin knots and curved like the roots of dog’s grass, but much thinner; they are fragrant, heat and prick the tongue. It grows on richly wooded mountains”.
“Al-Ghafiqi states that the original asarabacca is from Greece, although he quotes ibn Samajiin as saying that the best types are the Chinese and Spanish” (The medical formulary, or Aqrabadhīn, Al-Kindi, 1966).
This clearly shows the Chinese Asarum was known and used i the West, and that it was considered equivalent.
An Experimental History of the Materia Materia, Lewis, 1784″
The roots and leaves of asarum have a moderately strong, not very unpleasant smell, somewhat resembling that of valerian or nard ; and a nauseous bitterish, acrid taste. The roots given in substance, in doses of a scruple or more, prove strongly emetic and cathartic. The leaves have the same operation, but their dose or degree of force has not been precisely determined : according to some, they are of more activity than the roots.
It is said, that this emetic plant has been of service in serous disorders, and hurtful in melancholic cases: that in small doses, it promotes perspiration, urine, and the uterine flux: that tinctures made in spirituous liquors possess both the emetic and cathartic virtues of the asarum : but that the extracts, obtained by inspissating these tinctures, act only, and with sufficient mildness, by vomit; requiring to be given in as large doses as the plant in substance, to produce as plentiful evacuations: that infusions in water operate mildly both upwards and downwards : that by coction in water, the emetic power is first destroyed, and afterwards the purgative the decoction long boiled, or an extract prepared with a large quantity of water not acting at all by stool or vomit, but proving powerfully deobstruent, diuretic, &c. It is obvious, however,, as the activity of the asarum is diminished more and more by boiling, that both the decoction and the extract must be accompanied with one capital inconvenience, precariousness in point of strength.
The principal use of asarum among us is as an errhine. The root is one of the strongest of the vegetable substances commonly employed in this intention: a grain or two, snuffed up the nose, procure a large evacuation of mucus both from the nose and mouth, without provoking sneezing like the white hellebore root, or discovering any remarkable irritation. The leaves, though supposed to be stronger than the roots as emetics and cathartics, appear to be milder as errhines. Geoffroy relates, that after snuffing a dose of this errhine, he has observed the salutary discharge to continue for three days together, and that he has known a paralysis of the mouth and tongue cured by one dose: he recommends this medicine in stubborn disorders of the head proceeding from viscid matters, in palsies, and in soporific distempers. During its operation, the patient must carefully avoid cold; which is apt to produce pustules, inflammations, and swellings of the face, and sometimes more alarming symptoms. This herb is a principal ingredient in the cephalic or sternutatory powders of the shops: some take three parts of dried asarum and one of marjoram leaves, others equal parts of the dried leaves of asarum, marjoram, and marum syriacum, and dried lavender flowers. The empyrical herb snuffs have likewise the leaves of asarum for their basis, but often mixed with ingredients of a more dangerous nature.
