Warming the womb for fertility

Have you ever wondered why Chinese grandmas or your acupuncturist always rant about not drinking cold water, especially to women during their menstrual periods?

The cold can penetrate in the deeper layers of your body, namely your uterus, and cause a "cold womb".

It is a quite common phenomenon in the USA, where most people tend to indulge in iced beverages, raw foods like salads and sushi, and stay in air-conditioned rooms for long hours.

These lifestyle habits may eventually lead to a cold womb, and issues like painful periods with clots, or even infertility. Now, not all period pain and infertility is due to cold, but there are things you can do to prevent it from happening.

What is a "cold womb"

Western medicine equivalent: Luteal Phase Defect

Having a cold womb will indicate that during the luteal phase of your cycle, meaning the phase after ovulation. Your body basal temperature (BBT) can help track the fluctuations of hormones.

In the luteal phase, the ideal core temperature is higher than before ovulation. For women with a cold womb, the low second half of the BBT chart will reflect that progesterone level produced is not high enough or the luteal phase is shortened.

This is also known as a Luteal Phase Defect (LPD)

Herbal medicine for warming the uterus

Kidney Yang deficiency

Kidney Yang deficiency is one of the most prevalent patterns in infertility patients.

Kidney yang deficiency has a correlation with low progesterone levels and include symptoms such as feeling colder than those around you, cold hands and feet, low libido, back pain with menses, fatigue, frequent urination, and low BBT readings.

Formulas: You Gui Wan, Ai Fu Nuan Gong Wan (mugwort and aconite pill for warming the womb)

Blood & cold stagnation

Kidney Yang deficiency combined with Blood stagnation is an even more common disharmony. When Kidney Yang is not strong enough to maintain proper blood circulation in the uterus, the cycle of rebuilding uterine lining is less than optimal, which leads to dark clotty periods or even endometriosis.
