The Lemna Minor picture and modalities
Lemna Minor is above all a nasal-polyp and catarrh remedy. Its keynotes are a blocked, obstructed nose from polyps and swelling, thick or crusty and sometimes offensive discharge, loss of smell, and post-nasal dripping, all markedly worse in wet, damp weather. A homeopath weighs this polyp-and-catarrh, damp-aggravated pattern within the whole picture, always alongside medical assessment of the nasal obstruction.
Before you consider Lemna Minor
This is background information, not advice to self-treat. Nasal polyps, persistent blockage, loss of smell, and chronic or offensive nasal discharge need medical assessment, since they can have causes that require proper diagnosis. In homeopathy the right remedy and potency are chosen for the whole individual by a qualified practitioner. Homeopathy should complement, not replace, conventional care.
