The latest video in my ‘Poisonous Plants 1-2-1’ series is about Aristolochia clematitis, birthwort. This is quite a special plant because it has been responsible for a great many accidental poisonings and its misuse as a herbal medicine has also caused great harm.
The plant page in the A to Z section is one of the longest on this site because there is a great deal to its full story. It fits many of the key topics when considering poisonous plants.
Historically, it was used extensively because of the Doctrine of Signatures. It has been shown to have a cumulative effect with small doses over a long time being as harmful as a single large dose. And, today, there are still those who deny the extensive scientific evidence of its extreme toxicity and insist it can be used safely in Traditional Chinese Medicine.
