Ardha Matsyendrasana comes from the Sanskrit language; “ardha” is half, “matsya” is fish, “indra” is the ruler (king), and “asana” is pose.
This Asana simultaneously stretches the muscle on one side of the back and abdomen while contracting the muscles on the other side. It tones the nerves of the spine, makes the back muscles supple, relives lumbago and muscular spasms, and reduces the tendency of adjoining vertebrae to develop osteophytes. When practiced with care, it has proved beneficial for mild cases of slipped disc. Ardha matsyendrasana massages the abdominal organs, alleviating digestive ailments. It regulates the secretion of adrenaline and bile and is recommended I the yogic management of diabetes. Under special guidance it is used for the yogic management of sinusitis, hay fever, bronchitis, constipation, colitis, menstrual disorders, urinary tract disorders and cervical spondylitis, as long as it can be performed without any discomfort.
Caution: Women more than two or three months pregnant should avoid this asana, people suffering from peptic ulcers, hernia or hyperthyroidism should only practice this pose under expert guidance.
