[What is yohimbe]

Yohimbe is a tree that grows in Africa, and the natives there have used the crude bark and purified compound to enhance sexual desire and performance. Yohimbe has been used for centuries as an aphrodisiac. It has even been smoked as a hallucinogen. Nowadays, Yohimbe bark extract is mostly used to treat impotence for men and women.

When ingested, Yohimbe is assimilated into the blood stream, and Yohimbe’s energizing effects come from its ability to increase blood flow to the genitals - and this applies to both men and women.Aside from its aphrodisiac effects, new research also show that Yohimbe has powerful antioxidant effects.

Pneumococcal polysaccharide vaccine—the latest version is known as Pneumovax 23—is the first pneumococcal vaccine, the first vaccine derived from a capsular polysaccharide, and an important landmark in medical history. The polysaccharide antigens were used to induce type-specific antibodies that enhanced opsonization, phagocytosis, and killing of Streptococcus pneumoniae bacteria by phagocytic immune cells. The pneumococcal polysaccharide vaccine is widely used in high-risk adults. As a result, there have been important reductions in the incidence, morbidity, and mortality from invasive pneumococcal disease.
First used in 1945, the tetravalent vaccine was not widely distributed, since its deployment coincided with the discovery of penicillin. In the 1970s, Robert Austrian championed the manufacture and distribution of a 14-valent PPSV. This evolved in 1983 to a 23-valent formulation. A significant breakthrough affecting the burden of pneumococcal disease was the licensing of a protein conjugate heptavalent vaccine beginning in February 2000.
