What Chinese herbs are used to regulate amenorrhea?
Herbs commonly used in traditional Chinese medicine to regulate amenorrhea include Angelica sinensis (Danggui), Leonurus japonicus (Yimucao), Rehmannia glutinosa (Shudihuang), Paeonia lactiflora (Baishao), and Ligusticum chuanxiong (Chuanxiong). Detailed explanations are as follows:

1. Angelica sinensis (Danggui): Warm in nature, with a sweet and pungent taste. Its primary functions are nourishing blood, promoting blood circulation, regulating menstruation, and relieving pain. It nourishes qi and blood, unblocks meridians, improves blood flow, and helps restore normal menstrual cycles in cases of amenorrhea caused by deficiency of qi and blood or blood stasis.
2. Leonurus japonicus (Yimucao): Slightly cold in nature, with a bitter and pungent taste. It excels at activating blood circulation, regulating menstruation, promoting diuresis, and reducing edema. Particularly effective for amenorrhea due to blood stasis, it resolves blood stagnation in the meridians and promotes smooth discharge of menstrual blood, making it a commonly used herb for menstrual regulation.
3. Rehmannia glutinosa (Shudihuang): Slightly warm in nature, with a sweet taste. It nourishes yin, enriches blood, replenishes essence, and fills the marrow. Suitable for amenorrhea caused by yin deficiency of the liver and kidneys or insufficient qi and blood, it helps restore bodily yin and blood, nourishes internal organs, and provides the necessary physiological foundation for menstruation.
4. Paeonia lactiflora (Baishao): Slightly cold in nature, with a sweet and bitter taste. It nourishes blood, regulates menstruation, soothes the liver, and relieves pain. For amenorrhea caused by blood deficiency or liver qi stagnation, it nourishes yin and blood, alleviates liver constraint, balances qi and blood, and supports the restoration of regular menstrual cycles.
5. Ligusticum chuanxiong (Chuanxiong): Warm in nature, with a pungent taste. It activates blood circulation, moves qi, dispels wind, and relieves pain. It enhances the effects of blood activation and meridian unblocking. When combined with other menstruation-regulating herbs, it improves conditions of qi and blood stagnation and facilitates normal onset of menstruation.
Treatment of amenorrhea should begin with a proper diagnosis by a qualified physician to identify the underlying cause before selecting appropriate herbal remedies, which may be used individually or in formulated combinations. During treatment, maintain regular作息 (daily routines), eat a light diet, avoid emotional fluctuations, and attend follow-up visits regularly to adjust the prescription as needed. Do not self-medicate or take these herbs long-term without medical supervision.
