Since ancient times, people have been interested in herbs and their properties. Some used plants and their seeds to improve the taste of food, others saw spices increase the shelf life of food, and still others began to perceive them as medicines. Until recently, people did not know how to conduct meta-analyses and test scientific hypotheses, and therefore acted on a whim. A shaman, for example, could notice that a person in a fever drank a decoction of some roots and after some time was cured. Based on this observation, he concluded that the plant was medicinal.
Modern science has become more rigorous. Medicine is improving, and at every turn of development, we either confirm old methods of treatment, or find evidence that they are useless or even harmful, and abandon them. Seasonings have also gone this way, although you can still find recipes for mixtures for weight loss or articles about the unique healing properties of bay leaves.
Let's analyze from a scientific point of view: are spices really able to strengthen the immune system, are there any contraindications when using spices and how to introduce them into a healthy diet.
