Which plant's roots are known to produce hydrogen cyanide used in the treatment of scabies?

The roots of cassava are known to produce compounds that can release hydrogen cyanide when processed improperly. This plant, particularly the bitter variety, contains cyanogenic glycosides, which can yield hydrogen cyanide when they are hydrolyzed. In the context of treating scabies, certain traditional remedies have utilized extracts from cassava for their antiseptic and antifungal properties, even though the hydrogen cyanide itself is poisonous and must be handled with care. Proper processing and preparation can mitigate the toxic effects, allowing for its medicinal use.

In contrast, garlic is known for its antimicrobial properties, but it does not produce hydrogen cyanide nor is it associated with treating scabies. Foxglove contains cardiac glycosides, primarily used for heart conditions, and does not produce hydrogen cyanide. Lastly, mustard plants generally contain glucosinolates, which can have various health benefits, but they are not specifically linked to hydrogen cyanide production for treating scabies.
