Lin has a particular interest in women’s health, and she uses acupuncture and Chinese herbal medicine to treat a wide range of gynaecological and obstetric conditions.
In Chinese philosophy, yin-yang theory is the fundamental law of the universe. The inter-change between yin and yang explains everything. It applies to women’s menstrual cycle as well.
The balance between estrogen and progesterone ensures normal female reproductive ability. Disorders, such as irregular menstruation, endometriosis, even infertility, may occur when there is an imbalance between these two hormones.
Magically, there is a bridge over Traditional Chinese Medicine and conventional medicine. The changes of two hormones during different phrase of menstrual cycle correspond to the changes of yin and yang during each phrase. Details see chart below:
| Phrase | Predominant Hormone | BBT | Yin-Yang |
| Menstruation phrase | Estrogen | Low temperature | Yin grows |
| Post menstrual phrase(follicular phrase) | Estrogen | Low temperature phrase with lowest temperature | Extreme yin ready to transform to yang |
| Ovulation phrase | Estrogen Progesterone | Highest temperature | Yin has transformed to yang |
| Pre-menstrual phrase(luteal phrase) | Progesterone | High temperature | Yang grows |
Based on this theory, Chinese herbal medicine and acupuncture are tailored to each stage of menstrual cycle. Women are advised to record basal body temperature (BBT) seriously, alongside with quality of cervical mucus, characteristics of period, PMS symptoms, ovulatory sensation, breast tenderness, moods, and other physical and emotional signs.
