Can saffron be consumed every day?
Generally speaking, saffron is not recommended for daily consumption. The detailed explanation is as follows:

Saffron has blood-activating properties, and long-term daily consumption may disrupt the body's balance. Even for individuals in good health without specific needs, daily consumption might burden the body and cause discomfort such as dry mouth, heatiness, dizziness, and other adverse effects. For those with a bleeding tendency or a naturally hot body constitution, daily consumption may exacerbate existing symptoms and potentially lead to more severe health issues. Saffron should only be consumed daily in the short term and in appropriate amounts under professional guidance when there is a specific need for调理 (bodily regulation). Once symptoms improve, consumption should be immediately discontinued or the frequency reduced.
It is also important to note that each serving of saffron should be limited to 1–3 grams to avoid overdose. Continuous consumption should not exceed two weeks, after which there should be a break of one to two weeks before considering resuming. Pregnant women, women during menstruation, and individuals with abnormal blood clotting functions must not consume saffron. If gastrointestinal discomfort, insomnia, or skin redness occurs during consumption, it should be stopped immediately. If you intend to use saffron for bodily regulation, you must first consult a healthcare professional and develop a suitable consumption plan based on your individual constitution—daily consumption without guidance is not advisable.
