The article puts forward an opinion that there are identical or similar toxic components and poisoning action among close relative species of toxic medicinal herbs. These components, however, may vary in contents with different species. Many scientific examples are enough to prove that we can take treating, curing and preventative measures effectively only if we hold the conception that "Toxicity and poisoning action to each other may exist in close relative species of toxic medicinal herbs".
