The dermatitis and intense itching is caused by the fluids forced under the skin during the feeding and does not begin until after the chigger has dropped off. Some pharmacists recommend Tincture of benzyl benzoate as a good chigger itch reliever. Many of the various species cause either a scrub itch as an allergic reaction to the chiggers saliva, or transmit human disease organisms. Among the important chigger-borne diseases are scrub typhus or tsutsugamushi disease, which occurs in many east and southeastern Asian counties. The most common issue of chiggers infesting humans is the scabies or itch mite.
Most common areas affected are the hands and wrists.
Lymph is the clear, watery sometimes faintly yellow liquid that contains white blood cells and some red blood cells. It travels throughout the lymphatic system to return to the venous blood stream through the thoracic duct, and acts to remove bacteria and certain proteins from the tissues, to transport fat from the intestines, and to supply lymphocytes to the blood. Vertebrates are any animal having a backbone or spinal column. Includes mammals, fishes, reptiles, birds, and amphibians. Dermatitis is a skin disease.
