Late closure of fontanelle 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 late closure of fontanelle 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 late closure of fontanelle is often associated with poor bone development, weak limbs and hair loss in the pattern “Kidney Essence Deficiency”.
Once identified, patterns are treated using medicinal herbs, acupuncture, and other therapies. In the case of late closure of fontanelle we’ve identified that a herbal formula called Zuo Gui Wan can help treat the patterns behind the symptom.
In Chinese Medicine late closure of fontanelle is a symptom for the pattern "Kidney Essence Deficiency". Below is a small explanation for it with links for more details.

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".
