Introduction

Under normal circumstances, Niuhuang (Bezoar Bovis) is a calculus found in the gallbladder, bile duct, or hepatic duct of bovines (Bovidae animals). It is a traditional Chinese medicinal material with high pharmaceutical value. Artificially synthesized bovine bezoar is also available as an alternative. It should be noted in daily use that Niuhuang is primarily intended as a medicinal ingredient, not as a common food item. It should be used appropriately under professional guidance, and should not be taken arbitrarily or consumed in any product containing Niuhuang without instruction.

Under normal circumstances, bezoar is a calculus formed in the gallbladder, bile duct, or hepatic duct of bovines (Bovidae animals), and it is a traditional Chinese medicinal material with high therapeutic value. Artificial bezoar is also available as an alternative. Detailed explanation is as follows:

Natural bezoar forms under specific conditions and is scarce in supply, thus making it quite valuable. When inflammation or metabolic abnormalities occur in the bovine biliary system, components such as cholesterol and bilirubin in the bile deposit and coagulate gradually, forming stone-like substances known as natural bezoar. Natural bezoar typically appears oval or nearly spherical, with a surface color ranging from yellowish-red to brownish-yellow. It has a crisp and fragile texture with layered striations on the fractured surface. It emits a fresh aroma and has a slightly bitter but sweet aftertaste.

Artificial bezoar, on the other hand, is a synthetic substitute produced using cow bile powder, cholic acid, bilirubin, and other ingredients according to the composition of natural bezoar. It has a higher yield and more affordable price, and can substitute natural bezoar in most cases. Both natural and artificial bezoar possess effects such as clearing heat and detoxifying, and calming the nerves. They are commonly used in the preparation of related medicines to relieve specific symptoms.

It should be noted that bezoar is primarily used as a medicinal ingredient, not as a common foodstuff. It should be applied appropriately under the guidance of professionals. Do not arbitrarily use or consume products containing bezoar on your own.

What should be done if a child experiences nosebleeds due to excessive internal heat?

Children experiencing nosebleeds due to excessive internal heat (commonly referred to as "fire" in traditional Chinese medicine) mainly result from expanded blood vessels in the nasal mucosa. Nasal bleeding can occur after forcefully blowing the nose or picking the nose, which may damage the mucous membrane. When the amount of bleeding is small, after applying nasal packing and pressure to stop the bleeding, an ice pack can be applied to the head and face to constrict the blood vessels. Avoid forcefully blowing or picking the nose. Under a doctor's guidance, children can take heat-clearing medications such as Niuhuang Jiedu Pian (Calculus Bovis Detoxication Pill) orally. Eating more vegetables and fruits to supplement vitamins and fluids is also recommended.
