Zhu Ya Zao
Xi Xin

Both ingredients may be hard to obtain in the UK. The RCHM enacted a voluntary ban on Xi Xin although it is still legal to purchase. Zhu Ya Zao/Zao Jiao was listed in some suppliers catalogues at last check (2017) although it seems unlikely any modern practitioner is going to use 500g when this and Zheng Gu Shui are the only formulae I have seen it used in to date. Whether two alternatives such as Bai Zhi and Shi Chang Pu which also aromatically release the exterior and transform Phlegm will have the same effect will have to be seen.

Preparation: Equal proportions are ground into powder and blown into the nose. only a very small amount should be used.

Actions: Unblocks the gate (jaw) and opens the sensory orifices

Contraindications: Pregnancy, loss of consciousness due to abandonment disorders or hypertensive crisis, cerebral haemorrhage, or traumatic cranial injuries.

This is intended for temporary emergency use only. Once consciousness is restored or sneezing induced it should be discontinued.
