Strychnos extracts are derived from plants belonging to the Strychnos genus, which includes various species found in tropical and subtropical regions. It's important to note that the use of Strychnos extracts can be associated with potential health risks due to the presence of alkaloids, particularly strychnine, which is highly toxic. Strychnine is a well-known poison, and the misuse or mishandling of Strychnos extracts can have severe health consequences.
