Gelsemium: the plant that can cause convulsions, paralysis and asphyxia

Gelsemium comes in three flowering varieties – two native to North America and one to China. All three can be deadly. The most toxic variety of gelsemium, Gelsemium elegans, only grows in Asia, and is also known as “heartbreak grass”.

The first scientific insight into the poison, at the centre of the pre-inquest hearing into the death of Russian whistleblower Alexander Perepilichnyy, comes from Sir Arthur Conan Doyle.
