Book excerpt: First published in 1986, this book describes the most important medicinal plants in tropical West Africa and similar humid tropical climates. After a short introduction about early traditional medicine, the bulk of the book gives an account of locally occurring plants, grouped by their medicinal actions. Plants that affect the cardiovascular and nervous systems are discussed, as are those with antibiotic, insecticidal and molluscicidal properties. Those which affect the hormonal systems of humans are catalogued and so are others that act as adrenal-cortex, sex and thyroid hormones. There is a full botanical index, which includes the commonly found synonyms for many of the plants and the work is illustrated by the author's own water colours. It may be of particular interest and use to pharmacists, biochemists, botanists and pharmacologists and of great value to those who exploit locally available resources in treating diseases in tropical areas.
