Botanical Overview
Potato (Solanum tuberosum) is a flowering plant in the Solanaceae family. This plant has earned a place in traditional medicine through its consistent therapeutic benefits, recorded across multiple cultures. The nightshade family (Solanaceae) includes herbs, shrubs, and small trees with alternate leaves and star-shaped or trumpet-shaped flowers. The fruits are typically berries or capsules. Many species produce potent alkaloids including tropanes, solanines, and nicotine, making this family both medicinally valuable and potentially toxic.
