Insomnia is a common complaint. Physical causes f insomnia are comparatively few. In most cases, insomnia is a psychophysiological disorder, resulting mainly from the self-stimulation engendered y anxiety, worry, or depression. Sleeping pills are routinely used for treating this disorder, but their continuous use in chronic cases may cause adverse side or toxic effects. Herbal medicines and acupuncture can be effectively used as alternative measures.

Etiology and Pathogenesis
Insomnia is often caused by emotional or psychic disturbances. Anxiety and anger make the Liver depressed, and the depressed Liver qi may be transformed into fire, which interferes with the normal functions of the Heart. Excessive anxiety may also impair the Heart (mind) and the Spleen, and insomnia occurs due to inadequate supply of nutrients and blood to the Heart.
In the aged and the patients suffering from chronic diseases, qi and blood are insufficient to nourish the Heart, thus leading to palpitations and insomnia. Qi deficiency may also involve the Heart and the Gallbladder, impairing one's sleep and making one vulnerable to fright. Consumption of Kidney essence may break down the normal balance between the Heart and the Kidneys, and incoordination between the Heart and the Kidneys may also be manifested as insomnia.
