Lemna minor
Plant · Araceae
Lemna Minor acts especially upon the nostrils and is suited to patients with chronic catarrhal affections of the upper respiratory tract. The hallmark is putrid smell and taste with abundant crusts and nasal obstruction from polypi or oedematous swollen turbinates. Asthma arising from nasal blockage responds well.

- Post-nasal dropping
- Pain like a string from nostrils to ear

Characteristics
We owe this remedy, 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 < 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 < in wet …
