Lobelia Herb Benefits and Information

Lobelia Herb Benefits and Information

Lobelia (Lobelia inflata), also called Indian tobacco, has a long history of use in connection with respiratory health.

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.

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.
