Hi, Thanks for writing in. Miraqule capsule contains Coenzyme Q10 and other supplements which help in general health of the patient. It is recommended for every one and improves the general health by providing micronutrients. The remedy for dry mouth is to suck on lozenges frequently and this will stimulate salivation in the mouth. The cause for reduced salivation is the side effect due to surgery, chemotherapy and radiation therapy. The radiation given to the area affected by cancer has affected the salivary glands and therefore you are experiencing reduced salivation and dry mouth. Please drink adequate amounts of water and fresh fluids regularly and keep your mouth moist. Please do not worry.
