What are the symptoms of saffron drinking too much?

Saffron has the effect of activating blood circulation to remove blood stasis and detumescence in traditional Chinese medicine. Therefore, excessive drinking may lead to increased menstruation and even bleeding of oral and nasal mucosa. Secondly, saffron also has the effect of exciting nerves, stimulating smooth muscle of uterus and dilating coronary artery blood vessels. Therefore, excessive drinking may also lead to rapid contraction of uterus causing abdominal pain. At the same time, it may stimulate continuous excitation of nerves and increase blood flow of heart, thus causing insomnia and palpitations. In addition, saffron components are more complex, if too much drinking leads to accumulation of alkaloids and other components, it may also damage liver and kidney.
