Antiasthmatic Antispasmodic Diaphoretic Diuretic Emetic Expectorant Miscellany Nervine
Indian Tobacco was a traditional North American Indian remedy for a wide range of conditions[254]. Nowadays it is used mainly as a powerful antispasmodic herb in the treatment of respiratory and muscle disorders[254]. Acting also as a respiratory stimulant, Indian Tobacco is a valuable remedy for conditions such as bronchial asthma and chronic bronchitis[254]. The dried flowering herb and the seed are antiasthmatic, antispasmodic, diaphoretic, diuretic, emetic, expectorant and nervine[4, 7, 21, 46, 165, 171]. The plant is taken internally in the treatment of asthma, bronchitis, whooping cough and pleurisy[238]. This remedy should be used with great caution and only under the supervision of a qualified practitioner[7, 21, 165]. Excess doses cause nausea, vomiting, drowsiness and respiratory failure[238]. See also the notes above on toxicity. The plant contains the alkaline 'lobeline' which has proved to be of value in helping people to give up smoking tobacco[7, 200, 213]. It is contained in many proprietary anti-smoking mixtures where it mimics the effects of nicotine[238]. The alkaloids present in the leaves are used to stimulate the removal of phlegm from the respiratory tract[213]. When chewed, the leaves induce vomiting, headache and nausea - in larger doses it has caused death[213]. The alkaloids first act as a stimulant and then as a depressive to the autonomic nervous system and in high doses paralyses muscular action in the same way as curare[213]. Externally, the plant is used in treating pleurisy, rheumatism, tennis elbow, whiplash injuries, boils and ulcers[238]. The whole plant is harvested when the lower fruits are ripe and it is used fresh or dried[238].

Now available: PLANTS FOR YOUR FOOD FOREST: 500 Plants for Temperate Food Forests and Permaculture Gardens.
An important new book from PFAF. It focuses on the attributes of plants suitable for food forests, what each can contribute to a food forest ecosystem, including carbon sequestration, and the kinds of foods they yield. The book suggests that community and small-scale food forests can provide a real alternative to intensive industrialised agriculture, and help to combat the many inter-related environmental crises that threaten the very future of life on Earth.
