Aromatic plants are those that produce strong, pleasant scents due to essential oils found in their leaves, flowers, or stems. Common examples include lavender, rosemary, and basil. These plants are often used in cooking, perfumes, and traditional medicine, as their fragrances can enhance flavor and promote well-being. The essential oils extracted from aromatic plants have various applications, including aromatherapy, where they are used to improve mood and reduce stress. Additionally, many aromatic plants are valued for their insect-repelling properties, making them useful in gardens and homes to deter pests naturally.
