Schwabe News Volume 3| Issue 1 | February 2012

Parthenium hysterophorus

It is commonly called as bitter-broom, congress grass, escoba amargo. It is a plant up to 1.0 m in height, that is native to the American tropics, but also seen in almost all over India and other countries like Australia, parts of Africa, etc. In India, it was first present as a contaminant in imported wheat. Since then it is reported in this sub-continent to trigger allergies, specially air-borne contact dermatitis (ABCD) and is a common cause of pollen allergy. To counter its toxic and allergic effects, homoeopaths started using this drug in homoeopathic doses. Earlier E. P. Anshutz, A. Blackwood, W. Boericke, J. H. Clarke, A. H. Grimmer and others have reported on this drug. Recently a clinical verification1 with over 235 cases between 1990 and 1996 has been published. It further enlightens our knowledge on this drug.

Verified symptoms are as follows:

Asthma, respiratory distress, tubercular laryngitis, abnormal breath sounds, prolonged expiration, irritation on skin, itching and sinusitis. From 235 cases marked improvement was observed in 123 cases (51.13%), moderate improvement was observed in 52 cases (22.34%), Mild improvement was observed in 33 cases (14.04%), no improvement was observed in 6 cases (2.5%) and symptoms worsened in 7 cases (2.98%).1
