 Lobelia (Lobelia inflata), also called Indian tobacco,
has a long history of use with respiratory ailments, such as asthma,
bronchitis, pneumonia, and coughs. Lobelia was a common herb
prescribed by early North American doctors.
Lobeline, an
active constituent in the lobelia plant, is very similar to nicotine
in its effect on the central nervous system. Lobeline acts as a
relaxant overall while also dilating the bronchioles (air passages),
thereby increasing respiration and possibly helping the lungs. Its
anti-asthma activity consists of stimulating the adrenal glands to
release the hormone epinephrine, which causes the airways to relax.
Medicinal Indications of
Lobelia
Lobelia is used to treat the following
conditions and/or their symptoms:
- Asthma
- Chronic bronchitis
- Pneumonia
- Symptoms of smoking withdrawal
- Spastic colon
- Spastic muscle conditions
Lobelia may also be used
externally for treating diseases of the muscles, joints, and tendons
that involve inflammation and degeneration.
Forms of
Lobelia Herb
Lobelia is available in the following
forms for internal use:
- Dried herb
- Liquid extract
- Tinctures
Lobelia is also available in the following
forms for external topical application:
- Ointments
- Lotions
- Suppositories
- Plasters
Therapy should begin with the use of lower
dosages and increase depending upon the individual's
response.
Dosage and
Administration
The following are recommended adult
doses:
- Dried herb (infusion or decoction): ¼ to ½ tsp herb in 8 oz of
water, preferably mixed with other herbs; steep 30 to 40 minutes.
Take 2 oz four times per day. (This method is not preferred
because of lobelia's acrid taste.) The following are recommended
adult doses:
- Liquid extract (1:1 in 50% alcohol): 0.2 to 0.6 mL three times
per day
- Tincture of lobelia: 0.6 to 2.0 mL per day
Adjust the
recommended adult dose to account for the child's weight. Most
herbal dosages for adults are calculated on the basis of a 150 lb
(70 kg) adult. Therefore, if the child weighs 50 lb (20 to 25 kg),
the appropriate dose of lobelia for this child would be 1/3 of the
adult dosage.
