Over the summer I was reading Botanical Brain Balms, a book by Nicolette Perry and Elaine Perry on ‘medicinal plants for memory, mood and mind’. It brings together a wealth of information on plants that can help us sleep or stay calm, ease our pain, improve our memory, and even provide us with mind-altering experiences. Some of the plants are exotic, in that they won’t grow in the UK climate, but which you can find on the shelves of the health food shop, but many are familiar garden plants. Each entry contains a description of the plant and its habitat, a round-up of history and folklore, and the results of modern scientific research proving its effectiveness. You will also find the key ingredients (chemicals) that provide the effect, how to use the plant and any relevant safety notes. There are even some recipes, including a sage, pine and mint cleaning spray to improve memory and concentration, a happy face cream, and teas, biscuits and cocktails.
