Dysentery is an inflammatory disorder of the colon that results in diarrhea or passing of stools with mucus and is usually preceded by gripping abdominal pain. Sometimes blood is also present in the stools. In Ayurveda, it is known as pravahika, which means ‘tenesmus’ (feeling the need to empty the bowels).
Eczema is a disease characterized by skin rashes that have redness, swelling, itching, dryness, and flaking. The skin itches and when scratched results in a rash. In Ayurveda, this is known as vicharchika. It occurs when the immune system becomes unbalanced, so the condition is often associated with other allergic conditions like allergic asthma, hay fever, etc. Genetic factors, debility, climate, and psychological factors can dispose one to the condition.
When we use the muscles that can voluntarily be controlled, such as those of our arms and legs, they alternately contract and relax as they move. Muscles that support our head, neck, and trunk contract similarly in a synchronized fashion to maintain our posture. A muscle (or even a few fibres of a muscle) that involuntarily contracts is called a spasm. If the spasm is forceful and sustained, it becomes a cramp. A muscle cramp is thus defined as an involuntarily and forcibly contracted muscle that does not relax. This causes a visible or palpable hardening of the involved muscle.
