Hoarse voice 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 hoarse voice 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 hoarse voice is often associated with dry cough, dry throat and dry skin in the pattern “Lung Dryness”.
Once identified, patterns are treated using medicinal herbs, acupuncture, and other therapies. In the case of hoarse voice we’ve identified that a herbal formula called Bai He Gu Jin Tang can help treat the patterns behind the symptom.
In Chinese Medicine hoarse voice is a symptom for the pattern "Lung Dryness". Below is a small explanation for it with links for more details.

Lung Dryness is often treated with Bai He Gu Jin Tang, a herbal formula made of 10 herbs (including Lily Bulbs - Bai He - as a key herb). Bai He Gu Jin Tang 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 Lung and Kidney Yin".
