Can processed Pinellia (Qing Ban Xia) and black processed Aconite root (Hei Shun Pian) be used together?

Generally speaking, Qing Ban Xia (processed Pinellia) and Hei Shun Pian (Aconite root) should not be used together. The detailed explanation is as follows:

Qing Ban Xia has functions including drying dampness, resolving phlegm, relieving nausea and vomiting, alleviating distention, and dissipating nodules. Hei Shun Pian is used to restore yang, rescue from collapse, supplement fire and augment yang, dispel cold, and relieve pain. Qing Ban Xia and Hei Shun Pian fall within the category of the "Eighteen Incompatibilities" (Shi Ba Fan), which means there is a contraindication in their combined use. This principle of traditional Chinese medicine (TCM) states that certain herbs should not be combined, as doing so may cause adverse reactions or even produce toxic effects.

Combining Qing Ban Xia and Hei Shun Pian may lead to adverse symptoms such as cold extremities, nausea, and vomiting. Prolonged concurrent use may also impair liver and kidney function, and in severe cases, could even result in kidney failure. Therefore, prior to using Qing Ban Xia or Hei Shun Pian, it is essential to follow the guidance of a qualified TCM practitioner to ensure safety and efficacy.

In daily life, it is advisable to maintain healthy habits such as eating a balanced diet and engaging in moderate exercise, which can aid in disease recovery.
