Yes. Most certainly.

Pharmacology is the study of how drugs (pharmaceuticals) behave in a biological system. Namely the pharmacokinetics (effect of the biological system on the drug) and the pharmacodynamics (effect of the drug on the biological system) of a pharmaceutical of interest.

Gelsemium sempervirens is also known as yellow jasmine, false jasmine, wild woodbine, and Carolina jasmine.

Gelsemium is an extremely toxic herb because of the alkaloid component, related to strychnine, which exists in all parts of the plant.

The scientific or taxonomic name would be Gelsemium rankinii and Gelsemium sempervirens.

The term "pharmacology" has its origin in the Greek words "pharmakon" (meaning drug) and "logia" (meaning study of). Pharmacology is the study of how drugs interact with biological systems and how they can be used to treat diseases.
