The amount of brown sugar intake during menstruation is not enough to cause excessive internal heat, because the glucose tolerance during menstruation is improved. If you continue to drink a lot of brown sugar water, such as abortion and confinement, it may cause excessive internal heat, because vitamin B 1 will be consumed in the process of converting brown sugar into glucose, and the lack of B 1 will lead to symptoms of excessive internal heat such as aphtha. In order to avoid getting angry, postpartum and confinement women need to eat some coarse grains, beans, dried fruits, yeast, hard-shelled fruits, or celery leaves and lettuce leaves. As long as you eat coarse grains once a week (without fine grinding), you can hardly get angry.

The same is true for drinking brown sugar at ordinary times. Drinking brown sugar will get angry because vitamin B 1 is consumed in the process of converting brown sugar into glucose. Lack of B 1 will lead to symptoms of getting angry such as aphtha. Therefore, when drinking brown sugar, eat more fruits and vegetables, and supplement vitamin B 1 with whole grains will not get angry.
