Let's talk about menopause symptom. When we approach to 40 to 50 years old, some women shows hot flashes, night sweat and mood swing. And some women can function, but other women are influenced so much that they couldn't function normally. For instance, they are in the middle of the meeting, and suddenly hot flash comes, the heartbeat increase, and they start sweating and they have panic attack, they want to run out of the room. And acupuncture can help to restore the balance of estrogen and progesterone so that when menopause comes, we have fewer symptoms. We can still work pretty normally. Menopause is different among the different races. Asian woman have lower estrogen levels, so they have less menopausal symptoms. But other races could have severe hot flashes, and acupuncture helps them to cope with those difficult symptoms.
