How and Where Have Foods Been Used as Medicine in the Past?
The four ‘humors’In ancient Greece and Rome, nearly 2,000 years ago, it was believed that optimal body function relied on a balance between four main fluids or humors. These fluids were thought to have independent properties but were also closely linked to each other and overall body function. The four humoral fluids were: blood, yellow bile (choler), black bile and phlegm – each had a different role and they all needed to remain in balance in the body- too much or too little of one humor would result in illness.Many things were believed to influence the balance of humors within a person – things such as their age, the time of the year, their gender and occupation and the place where they lived. Through food and drink as well as by the process of ‘blood letting’ the humors were corrected and rebalanced.People were advised to eat different foods not only when they were ill but also when they were “weak of character” for example if they were particularly depressed or angry because mood and disposition was also thought to be affected by humoral balance. These practices were highly individualised, and generally limited to people of affluence. This Graeco-Roman way of thinking about health, as modified by Arab doctors, was imported into Europe in the Middle Ages. Here it lasted until the early Renaissance when people started to gain more knowledge of how bodies functioned and the causes of disease.

Food as Medicine
Plant foods as medicinesAcross history, many fruits and vegetables and other plant foods have been used, recommended and/or avoided for their supposed medicinal properties. As one example, when the Tudor boy king Edward VI was dying of tuberculosis, he was given: spearmint syrup, red fennel, liverwort, turnip, dates, raisins, mace, and celery mixed with raw meat from a 9-day old female piglet.Often particular fruits and vegetables were considered to have particular special properties. For example, people were encouraged to avoid eating too many cucumbers and melons as these are very watery foods and so it was thought that they would encourage fluid retention.Fruits such as figs, pomegranates and quinces were often considered be very beneficial to health but if you did not live around the Mediterranean region, these were accessible only to the wealthy. Okra, a green, finger shaped vegetable common in Indian cooking, was believed to be effective for assisting with managing diabetes as was bitter melon among Chinese people.In more recent times, cranberries have been regarded as a useful treatment against urinary tract infections although the evidence supporting this is scanty.
In EuropeIn old traditional European diets in countries like Greece, wild greens played an important role. Young leafy shoots and leaves were collected from a great variety of plants including thistle, dandelion, amaranth, stinging nettle, mallow and purslane found growing wild in the countryside. These were eaten raw or boiled and served with lemon juice and olive oil. They were believed to be very important for good health and for recovering from illnesses. Dandelion and sow thistle were used to treat fluid retention.Stinging nettles which are high in vitamin C were used to treat scurvy and anaemia. Spiny chicory (Stamnagathi), a leafy green common in Crete, was boiled and used to treat stomach ache. It is now known that most of these edible wild greens provide a rich source of vitamins and micronutrients. In southern Herzegovina, 18 different wild vegetables were still found to be used in this way today.
In AsiaAnother example and an interesting case study to consider when thinking of food being used as medicine is that of the Okinawan people who are one of the longest living people in the world. The Okinawans have strong beliefs and practices about food and diet. They believe certain foods to have many medicinal qualities linked to longevity. As they live on the Ryukyu Islands between Japan and China, the Okinawans have been strongly influenced by China and Chinese ideas of longevity achieved through diet.Historically the highest ranking doctor in Chinese medicine, was the diet doctor. Okinawans believe that ‘food maketh the man’ and that the food they eat is ‘nuchi gusui’, or ‘medicine for life’. You can research more about the Okinawan diet and how it is changing.
Comfort foodsWe should also think about specific foods or combinations of food that comfort us when we are unwell. Like foods used as medicines, this also will vary across families and across cultures. Chicken soup and its various different permutations and combinations is one example of a food that has been used as part of the medicinal health in times of feeling unwell.From ancient Chinese history and across many Asian countries and further afield into Europe, congee or a slow cooked rice porridge has been used for invalids, because it is believed to be easily digestible.Congee may be served fairly plain or it may be flavoured with a range of different proteins – chicken, pork as well as herbs and spices.
