Also known as 'Indian Tobacco', Wild Tobacco or Aztec Tobacco, in small doses this medicinal herb acts as a stimulant, especially on the respiratory system. In larger doses it acts as a nerve depressant, and is useful for asthma and whooping cough. Use with caution as excessive doses can cause severe depression.
This annual herb is easy to grow in well drained soil. Lovely yellow flower in mid summer, and makes an interesting garden plant.
