Too old people are not fit to eat saffron. The main reason is that their immune level is relatively poor, and a little toxicity may not harm the body. In addition, they may not be able to take saffron correctly. When some younger generations are away, if you eat saffron at will, it may lead to some adverse reactions and have a negative impact on the physical condition of the elderly, so it must be avoided.
Friends with serious diseases are not suitable for eating saffron. The most important reason is that some products, especially Chinese herbal medicine products, may be rejected in this part of the patient's body, which may have a certain impact on human metabolism. So even if they really want to eat, they must take it under the guidance of a doctor to avoid unnecessary trouble. Every friend with other diseases should consult a doctor in advance, which will be more reliable.
