    What does it do?

    From the perspective of Traditional Chinese Medicine (TCM), general signs of blood deficiency include dry skin, pale complexion, poor sleep, menstrual cycles with scanty flow, lightheadedness, dry stool and/or lack of energy. Blood deficiency is particularly common in women due to the loss of menstrual blood. Si Wu Tang Pian strongly addresses blood deficiency, with emphasis on Liver blood.

    The Liver in TCM is responsible for maintaining a normal menstrual cycle. Si Wu Tang Pian is particularly suited to cases of blood deficiency with menstrual irregularities. Si Wu Tang Pian regulates the Chong Mai and Ren Mai, major meridians associated with reproduction. The Heart also depends on sufficient nourishment from Liver blood.

    Si Wu Tang Pian is an important formula in cases presenting with the above symptoms and a pale tongue and a thin pulse.

    Si Wu Tang Pian is an elegant, foundational blood tonic formula composed of just four Chinese herbs. The herbs in this formula fall into two groups, based on the role they play in the formula. The first group, consisting of Shu Di Huang (Rehmannia root) and Bai Shao (Peony), directly tonify the blood. Shu Di Huang has a powerful tonifying effect on the blood and Yin, particularly of the Liver and Kidneys. Shu Di Huang also tonifies the Jing or essence. Bai Shao also nourishes the Liver.

    The second group of herbs, consisting of Dang Gui (Chinese Angelica Root) and Chuan Xiong (Szechuan Lovage Root), regulate the Qi of the blood to dispel and prevent blood stasis, which often develops from blood deficiency. Dang Gui tonifies the blood without cloying and even invigorates the blood, a rare combination for herbs in the blood tonic category. Chuan Xiong is a blood-invigorating herb, well known for its ability to address issues of menstrual cramp associated with insufficient Qi and blood circulation.

    Together, these four medicinals compose an elegant, well balanced and highly regarded Classical formula for the treatment of blood deficiency.

    Rated 5 out of 5 by from Great for irregular periods... My teenage daughter was prescribed this formula along with Nuan Gong Yun Zi Pian, by our Acupuncturist, for an irregular menstrual cycle (up to 2.5 to 3 months apart). She started with 10 capsules per day of the Si Wu Tang and 12 per day of the Nuan Gong Yun Zi. After about 2 to 3 months her period starting arriving about every 7 to 8 weeks, then eventually it was about 40 to 45 days apart. Then her cycle came early; 25 days apart. We then stopped the daily dose and lowered the amounts.She took the herbs 3-4 times per week. Her cycle is currently at between 30 to 35 days apart. This was a journey of about 1 year to get to this point.

    Rated 5 out of 5 by from Excellent product My mother has been taking it for general well being for quite some time. She is very happy with the results. She is over 70 and her health is basically fine. However she was advised to add this product to supplement her diet. She has noticed a big improvement in digestion over the months and she has more energy. She is very satisfied and will continue to use it.
