Introduction
Whether 10 grams of processed Pinellia (Banxia) causes poisoning depends on its processing method and herbal compatibility. If standardized processed Pinellia is used, and administered under the guidance of a TCM practitioner with proper formulation according to individual constitution and condition, a 10-gram dose falls within the normal therapeutic range. Most people will not experience toxic reactions and can benefit from its intended medicinal effects—such cases generally do not warrant excessive concern.

Under normal circumstances, whether 10 grams of processed Pinellia (Banxia) causes poisoning depends on its processing method and herbal compatibility. When properly processed and used appropriately, it is generally safe; however, the raw form or improper use may lead to poisoning. If in doubt, it is recommended to consult a healthcare professional in advance. Detailed analysis is as follows:

If the Pinellia used has been properly processed according to standard procedures and is prescribed by a licensed TCM practitioner based on individual constitution and medical condition, a dosage of 10 grams falls within the typical therapeutic range. Most individuals will not experience toxic reactions and can benefit from its intended medicinal effects—such cases generally do not require excessive concern.

However, if the Pinellia is inadequately processed, self-administered without medical guidance, used without considering potential drug interactions, or if the individual is particularly sensitive to Pinellia species, even a 10-gram dose may trigger poisoning symptoms such as nausea, vomiting, and throat irritation. These situations require caution.

Prior to using processed Pinellia, ensure the herb has been correctly prepared. Always use under the supervision of a qualified TCM practitioner—do not purchase or consume it independently. If any adverse reactions occur during treatment, discontinue use immediately and seek medical attention, informing the doctor of your medication history for timely management.
