Why does my tongue go numb after taking Heishunpian? What should I do?

Tongue numbness after taking Heishunpian (Aconiti Lateralis Radix Praeparata) may be caused by drug irritation, insufficient decoction time, peripheral neuritis, fungiform papillitis, or acute aconitine poisoning. This can be improved through general treatment, medication, and other methods. It is recommended to seek medical attention promptly and undergo treatment under the guidance of a physician.

1. Drug irritation: Heishunpian contains aconitine, which, although reduced in toxicity after processing, may still directly irritate the oral cavity, causing tongue numbness and mild burning sensations, typically transient. It is recommended to take the medication after meals to reduce irritation and rinse the mouth afterward. If numbness persists or worsens, discontinue use and seek medical attention.

2. Insufficient decoction time: Aconite must be boiled first for 30-60 minutes to degrade aconitine. If the boiling time is too short, residual toxic components may cause tongue numbness and lip tingling. Strictly follow medical instructions to extend the decoction time. Decoct initially until there is no numb sensation upon tasting, then continue boiling with other herbs to ensure complete degradation of toxicity.

3. Peripheral Neuritis: Peripheral nerve damage caused by diabetes, vitamin B deficiency, or other factors can increase sensitivity to drug irritation, manifesting as tongue numbness accompanied by hand and foot numbness and pain. It is recommended to take medications such as mecobalamin tablets, vitamin B1 tablets, and alpha-lipoic acid capsules under a physician's guidance to alleviate symptoms.

4. Fungiform papillitis: Poor oral hygiene or spicy irritation can cause inflammation, congestion, and swelling of the tongue papillae, which may be exacerbated by Heishunpian, resulting in tongue numbness, burning pain, and papillary swelling. Patients may use chlorhexidine mouthwash, Kangfuxin liquid, and compound vitamin B tablets under medical guidance to relieve discomfort.

5. Acute aconitine poisoning: Overdose or improper processing of aconite can cause aconitine to irritate nerve endings, initially presenting as tongue and lip numbness, accompanied by dizziness and palpitations. Immediately stop taking the medication and seek emergency medical care. Follow medical advice to administer atropine injection, lidocaine injection, glucose injection, and other medications for detoxification and symptomatic treatment.

During medication, closely monitor physical reactions, and promptly seek medical attention and consult a physician if any discomfort occurs. In daily diet, maintaining a balanced dietary structure and diverse food intake is recommended to help sustain good health.
