John Locke (1632-1704), physician and philosopher, is best known for his Essay Concerning Human Understanding (1690). His reputation as a philosopher has overshadowed the extent of his medical interests. Locke's journals between 1678 and 1698 contain thousands of items of medical interest.
An entry in his journal for September 1684 contained the following recommendations for the care of the newborn infant.1
1. Soon after birth the baby can be given 1 or 2 spoonfuls of syrup of violets with almond oil, to loosen the bowels and keep it from convulsive colic. Or else distilled olive oil can be mixed with sugar.
2. If the newborn baby is in a weak condition you can blow on it the smell of chewed onions and cloves; smear its nostrils and lips with Cinnamon water; press warm slices of meat on its head and anus; wrap in bandages soaked in red wine and place in a bath composed of water or beer and fresh butter. If the baby is lively give a little after a mixture of 1 spoonful of distilled almond oil and syrup of Cowslip flowers and ½ spoonful of wine tempered with sugar, so that it can purge itself properly.
3. As soon as it begins to feed on pap, give it for the first few days a little powder of Marchion.
4. If it is weak apply to the region of the heart a cloth coaked with warm Embryon. The best ways to stimulate its strength are baths, putting warm wine on its head, placing hot meat on its chest, smearing its nose and lips with cinnamon water, putting onions near its nostrils, etc.
