Introduction
The mouth is swollen due to “excess internal heat” (a TCM concept). In Traditional Chinese Medicine (TCM), treatment primarily involves using patent herbal medicines that clear heat and detoxify, such as Huanglian Jiedu Pian (Coptis Decoction for Heat-Clearing and Toxin-Resolving) or Yiqing Capsules, which help clear heat, eliminate toxins, reduce swelling, and promote toxin elimination. Alternatively, the herbal formula Wuwei Xiaodu Yin (Five-Ingredient Detoxifying Decoction) may be modified and administered orally. Its main ingredients include *Honeysuckle* (Lonicera japonica), *Forsythia* (Forsythia suspensa), *Dandelion* (Taraxacum mongolicum), *Viola yedoensis*, and *Sedum aizoon*. The herbs are decocted in water to yield 200 mL, taken orally twice daily.
Blisters on the mouth are commonly caused by “excess internal heat” (a traditional Chinese medicine concept). According to TCM theory, “excess internal heat” reflects an imbalance between Yin and Yang in the body, resulting in excessive internal fire that may affect any of the five zang-organs or six fu-organs. For instance, heart-fire may cause oral ulcers and restlessness; liver-fire may lead to facial flushing, red eyes, irritability, and quick temper. Blisters on the lips represent just one possible manifestation of this condition. So, what should you do if your mouth swells due to “excess internal heat”?
What to Do When Your Mouth Swells Due to “Excess Internal Heat”
Swelling of the mouth caused by “excess internal heat” can be managed using both TCM and Western medical approaches. In TCM, treatment primarily involves herbal formulas or patent medicines with heat-clearing and detoxifying properties—such as Huanglian Jiedu Pian (Coptis Decoction Tablets) or Yiqing Capsules—to clear internal heat, eliminate toxins, reduce swelling, and promote detoxification. Alternatively, Wuwei Xiaodu Yin (Five-Ingredient Detoxifying Decoction), modified according to individual needs, may be prescribed orally. Its main ingredients include honeysuckle flower (Jinyinhua), forsythia fruit (Lianqiao), dandelion (Pugongying), violet (Zihuadiding), and purple-backed beggarticks (Zibeitiankui); decocted in water to yield 200 mL, taken twice daily.
Fresh purslane (Ma Chixian) and yam root (Diyu) may also be decocted and applied topically as a cool, moist compress to the affected area, exerting effects of cooling the blood, reducing swelling, and detoxifying. From a Western medical perspective, if bacterial infection is responsible for the swelling, oral roxithromycin capsules may be prescribed for antibacterial therapy. If the condition is caused by a viral infection such as herpes simplex, antiviral treatment with valacyclovir hydrochloride granules may be recommended.
In daily life, consider drinking heat-clearing teas such as chrysanthemum tea or jasmine tea. Increase intake of fruits and vegetables rich in vitamin C, while avoiding spicy, heat-inducing foods. Ensure adequate sleep and engage in regular physical exercise to strengthen immunity. We hope this information proves helpful!
