Guava, also known as guava, can be eaten by women during menstruation. Guava is a tropical fruit, rich in nutrients and vitamin C. Guava has anti-inflammatory and anti-emetic properties, so women should not eat too much of it during their periods, as eating too much may lead to a decrease in the amount of menstrual blood and trigger dysmenorrhea in women. Women should avoid eating cold fruits during menstruation because they can cause bruising, which is detrimental to the discharge of menstrual blood and can lead to dysmenorrhea. During menstruation, it is important to keep warm and not to catch a cold, and to pay attention to personal hygiene, washing the vulva every day to avoid infection.
