Parthenium allergy is caused by direct and indirect contact with Parthenium hysterophorus L. of the Compositae family, accidentally introduced into India from the USA 20 years ago. Its distribution was supported by the optimal environmental conditions of this country. It causes severe contact dermatitis in a lot of people, which becomes chronic after longer exposition. The source of the epidemic are the strong sensitizing sesquiterpene lactones parthenin, ambrosin and others, which are highly concentrated in the trichomes of the plant. During the dry season in India the mature plants crumble to a fine dust, that is scattered by the wind and becomes disseminated throughout the countryside. Permanent contact with this dust is the source of this socalled "airborne contact dermatitis". About 12 deaths occurred in severely affected persons due to intercurrent infection. Control of Parthenium hysterophorus is possible with Ansar-529, a weed-killer containing arsenic. Recently the weed has been introduced into Central-Australia too.
银胶菊过敏是由直接或间接接触菊科银胶菊引起的，这种植物于20年前从美国意外引入印度。该国适宜的环境条件促使了它的传播。它会使许多人患上严重的接触性皮炎，长时间接触后会转为慢性。这种流行病的源头是具有强烈致敏性的倍半萜内酯类物质，如银胶菊素、豚草素等，这些物质高度集中在植物的毛状体中。在印度的旱季，成熟的植株会碎成细粉，随风飘散，散布到整个乡村。持续接触这种粉尘是所谓“空气传播性接触性皮炎”的根源。严重感染者中约有12人因并发感染而死亡。使用含有砷的除草剂安萨尔-529可以控制银胶菊。最近这种杂草也被引入了澳大利亚中部。
