Notes:
This formula is always going to generate controversy due to its use of rhino horn. These were considered magical creatures in ancient China, the equivalent of a unicorn, whose horns could detect and detoxify poison. It seems unlikely it was ever intended for widespread use. Given the symptoms indicated it seems like the Tang dynasty physicians were pharmacologically helpless against such a severe presentation and resorting to magical cures.

Whatever the origin of this formula it should no longer be used. Patients with the original presentation should be in emergency care. It remains in use as the other ingredients and the substitutions can be useful as a base in disorders of Blood level Heat with similar presentations such as frequent nosebleeds or bleeding skin conditions with red tongue and rapid pulse.
