Below are the main rubriks (i.e strongest indications or symptoms) of Lemna Minor in traditional homeopathic usage, not approved by the FDA.



A catarrhal remedy. Acts especially upon the nostrils. Nasal polypi; swollen turbinates. atrophic rhinitis. Asthma from nasal obstruction; worse in wet weather.

Duckweed. N. O. Lemnaceae or Pistiaceae. Tincture of the whole fresh plant.

We owe Lemna Minor, the common duckweed, with its brilliant green leaf and bladder-like float, to Dr. Cooper. Some tentative clinical experiments proved to him that Lemna had a very definite affinity for the nose, acting beneficially in cases of nasal obstruction and catarrh with or without polypus. Foul smell from the nose and foul taste in the morning on waking are indications.

also agg. in damp weather, and especially in heavy rains. Burnett has recorded several cases of polypus in which immense relief was given by Lemna by shrinkage of the swelling, but not actual cure. On this Cooper remarks "In bad cases of nasal polypi the tendency is to the growths filling up the cavities formed by removal, and, consequently, relief often appears temporary, when the case only requires repetition of the Unit Dose." Asthma from nasal obstruction agg. in wet weather has been cured by it. I removed with Lemna 3x four times a day a very chronic catarrh in a lady, and at the same time made her tolerant of the smell of strong-scented flowers, which she could not bear before. In a man I cured with Lemna 3x, given three times a day, an aggravated nasal catarrh. In the morning he filled two pocket-handkerchiefs with yellow defluxion before he could get his nose clear. Cooper gave in all his cases single doses of the Ø tincture, allowing them to expend their action before repeating. In three of his cases diarrhoea was set up. Shearer (Hom. Eye, Ear, and Throat Jour., 1895) found Lemna the best remedy in atrophic rhinitis, when crusts and muco-purulent discharge were very abundant. The Schema is made up of cured symptoms, and symptoms produced in patients.


Third to thirtieth potency.
