In Ayurveda, langhana is one of the six
principles of treatment and is a type of shodhana chikitsa,
or cleansing therapy. Its purpose is to relieve the body of
heaviness, making the body light.
Langhana treatment is typically
recommended for diseases or conditions in which there is a heaviness
or an obstruction, such as diabetes, sinusitis, asthma, indigestion,
obesity, high cholesterol, fever and constipation. Langhana
treatments are divided into two categories:
- Shodhana (purification), which
removes imbalanced doshas (biological energies). This
treatment includes enemas, nasya sinus treatments procedures,
and detoxification, among others.
- Shamana (palliative), which
transforms doshas from abnormal to healthy. Such treatment includes
herbal therapy, physical exercise, exposure to sun, and avoiding
unhealthy food and drink.
