Are Any Mint Family Plants Poisonous? Exploring Their Safety

Are there any varieties of mint that can be toxic to animals? Indeed, one such plant is Perilla mint (scientifically known as Perilla frutescens). This herbaceous plant has a shallow taproot and a network of fibrous roots. In Tennessee, it poses a significant threat to cattle and has been responsible for more cattle deaths than any other toxic plant in the region. Perilla mint is highly toxic to cattle, other ruminants, and even horses. All parts of the plant contain toxic compounds, with the flowering structures being particularly dangerous. As a result, it is crucial for livestock owners and caretakers to be aware of the risks associated with Perilla mint and take measures to prevent their animals from grazing on this poisonous plant.

Not all varieties of mint plants are suitable for consumption. While some types of mint are cultivated specifically for culinary purposes, others are primarily ornamental and not intended for eating. To determine if a mint plant is edible, a reliable method is to assess its aroma. On August 21, 2023, this question was addressed to clarify the edibility of different mint varieties.
