Automated equipment to carry out complete blood counts was developed in the 1950s and 1960s. The cells that circulate in the bloodstream are generally divided into three types: white blood cells (leukocytes), red blood cells (erythrocytes), and platelets (thrombocytes).

DMSO is a simple chemical made from wood pulp that penetrates the skin and and has demonstrated the ability to promote the healing of pockets of inflammation.MSO, however, is the relatively inexpensive by-product of the wood pulping process and has been in the public domain too long to be subject to proprietary claims. Pharmaceutical companies therefore have no incentive to bring DMSO through the approval process.
