Hypertension

by
Hypertension

Hypertension, or high blood pressure, is a common condition in which the force of blood against the artery walls is consistently too high. Over time, this increased pressure can damage blood vessels and lead to various complications, including heart disease, stroke, and kidney failure. Blood pressure is measured in millimeters of mercury (mm Hg) and … Read more

potash alum

Preparation of Potash Alum: It is typically prepared by the reaction of aluminium sulphate with potassium sulphate: Al2(SO4)3 + K2SO4 → 2KAl (SO4)2 Properties of Potash Alum: A colorless, odorless, crystalline compound. Soluble in water. Commonly found as a dodecahydrate (KAl(SO₄)₂·12H₂O), forming translucent, colorless crystals. Uses Astringent: Used in skin care products, mouthwashes, and aftershaves. … Read more

Astringents

by
Astringent

Overview of Astringents: Astringents are substances that cause the contraction or shrinkage of tissues, helping to dry out and tighten the skin. Commonly used in dermatology, cosmetics, and some medical treatments. They work primarily by precipitating proteins on the skin surface or mucous membranes, leading to reduced tissue permeability, inflammation, secretion, and bleeding. Mechanism of … Read more
