Step-by-step explanation:
The drug phloroglucinol is not mentioned in the reference information provided, but it is commonly used as an antispasmodic to treat spasms of the stomach, gut, and bladder. It is not an herbicide, germicide, antifungal, antiprotozoal, or part of allergy medications. If the student is asking about phloroglucinol for a school assignment related to its uses as a medication, it is important to note that phloroglucinol works by relaxing the smooth muscles of these organs to relieve pain and cramping.
