Are alum and alum the same

Alum and alum are the same substance, commonly known as potassium aluminum sulfate dodecahydrate.

Alum is a commonly used name in the fields of traditional Chinese medicine and chemical engineering. Its chemical composition is hydrated aluminum potassium sulfate, which appears as colorless transparent crystals or white crystalline powder. It has the effects of astringency, hemostasis, dryness and itching relief. In traditional Chinese medicine, it is commonly used to treat conditions such as eczema and hemorrhoid bleeding, and can be formulated as a solution or powder for external use. The name alum emphasizes its physical properties and is named after its snow white color after extraction. It is commonly used for water purification in food processing or traditional tofu production. The two are completely identical in terms of chemical composition and medicinal value, with the only difference being the naming angle.

Attention should be paid when using alum or alum. Excessive oral intake may lead to aluminum poisoning, manifested as nausea, vomiting, or neurological symptoms. Excessive external concentration can easily cause skin irritation. It is recommended to follow medical advice to control the dosage. Use with caution for individuals with yin deficiency and internal heat, as well as pregnant women. Do not use for those with renal insufficiency. When storing, it should be placed in a dry place to prevent moisture and avoid contact with alkaline substances.
