The different parts of many plants have been used since ancient times for medicinal purposes. History records many such observations.
The first plant is
Caesalpinia pulcherrima plant. It is commonly seen in India. The studies note, contains compounds that have powerful antiviral benefits, especially effective against human herpes viruses and adenoviruses,
which cause the common cold. Caesalpinia pulcherrima prevents these viruses from replicating. Other recent studies demonstrate that extracts from the flower, stem, leaf, fruit, root, and seed of Caesalpinia pulcherrima are also effective against wheezing, bronchitis, malarial infection, tuberculosis, other bacteria, fungi, and some parasites.’ (Counter, 2006)
Second plant is Flos pavonis. Some of its parts were used by the slave women to induce abortion. The Indian slave women are very badly treated by their white enslavers and do not wish to bear children who must live under equally horrible conditions. The black slave women, imported mainly from Guinea and Angola, also try to avoid pregnancy with their white enslavers and actually seldom beget children. They often use the root of this plant to commit suicide in the hope of returning to their native land through reincarnation, so that they may live in freedom with their relatives and loved ones in Africa while their bodies die here in slavery, as they have told me themselves.’ (Merian, quoted in Counter, 2006)
