Erectile dysfunction can be the consequence of several so-called “patterns of disharmony” in Chinese Medicine.
Chinese Medicine sees the body as a system, not a sum of isolated parts. A "pattern" is when the system's harmony is disrupted, leading to symptoms or signs that something is wrong (like erectile dysfunction here). It is similar to the concept of disease in Western Medicine but not quite: a Western disease can often be explained by several Chinese patterns and vice-versa.
A pattern often manifests itself in a combination of symptoms that, at first glance, do not seem necessarily related to each others. For instance here erectile dysfunction is often associated with poor bone development, late closure of fontanelle and weak limbs in the pattern “Kidney Essence Deficiency”.
Once identified, patterns are treated using medicinal herbs, acupuncture, and other therapies. In the case of erectile dysfunction we’ve identified that a herbal formula called Zuo Gui Wan can help treat the patterns behind the symptom.
Kidney Essence Deficiency, a "pattern of disharmony" that can cause erectile dysfunction
In Chinese Medicine erectile dysfunction is a symptom for the pattern "Kidney Essence Deficiency". Below is a small explanation for it with links for more details.

Kidney Essence (Jing 精) Deficiency usually involves Deficiency of Kidney Yin and, to some extent, Kidney Yang. Its symptoms are typically in relation to growth, development, reproduction, sexuality, bones, marrow, the brain, teeth, memory and hair.
In addition to erectile dysfunction, other symptoms associated with Kidney Essence Deficiency include poor bone development, late closure of fontanelle and weak limbs.
Kidney Essence Deficiency is often treated with Zuo Gui Wan, a herbal formula made of 8 herbs (including Prepared Rehmannia - Shu Di huang - as a key herb). Zuo Gui Wan belongs to the category of "formulas that nourish yin and tonify", which might be why it is often recommended for this pattern. Its main action as a formula is: "Nourishes the Yin".
