Native Americans used Lobelia across the continent for many purposes. In many modern spiritual traditions, it can be used to banish malevolent spirits, negative energies, ghosts and help enhance positive energy. A good ingredient for mojo, gris-gris, or protection pillow.
Lobelia is also used for breathing problems including asthma, bronchitis, whooping cough, and shortness of breath (apnea) in newborn infants. Some people take lobelia as a sedative to help them relax. Other people use it to increase sweating.
Lobelia is applied to the skin for muscle pain, joint lumps associated with rheumatoid arthritis (rheumatic nodules), bruises, sprains, insect bites, poison ivy, and ringworm.
