People who benefit most from this remedy may have difficulties in connecting to or becoming intimate with others and may withdraw, even from close friends. Mental activity may cause them great exhaustion, and they may be very forgetful. Great weakness, particularly if the body temperature increases, is a classic feature associated with this remedy. It is used for conditions such as chronic fatigue syndrome and multiple sclerosis, when there is rapid mental and physical exhaustion, with unhealthy-looking skin, emaciation, constipation, hair loss, and possible malfunction of the nerves governing the genitourinary tract.
