As all autumn hay fever sufferers know, this plant’s bright yellow flowers cause (and thus cure homeopathically) thick, yellow, ropy mucus, everywhere – from ears, eyes and throat to stomach, and other organs. Profuse thick yellow expectoration in the throat and chest sets off its stubborn cough. It also aids general and muscular weakness, defective digestion, constipation and hemorrhoids – usually in sluggish or elderly systems. Hydrastis conditions feel better resting and worse breathing in cold air or washing.
