Peppermint
Mentha piperita
Русское название: Мята перечная
An aromatic mint hybrid known for menthol-rich oils. Leaves are used in cooking and drinks, but concentrated essential oil is not equivalent to culinary mint. Plants spread readily by underground stems.

Do not use photographs or online summaries to identify wild plants for eating or medicinal use. Some poisonous plants resemble edible species and even handling certain species can cause harm. If poisoning is suspected, contact your local poison service or urgent medical care. Do not wait for symptoms.
