Honey for cough
Honey can soothe throat irritation and may reduce cough frequency in some people. It should never be given to a child under 12 months because of the risk of infant botulism. A cough with breathing difficulty, chest pain, blood, high fever or prolonged symptoms needs assessment.
Ginger for nausea
Ginger has been studied for nausea, including pregnancy-related nausea and motion sickness, with mixed but generally encouraging evidence. Large amounts or concentrated supplements can cause stomach upset and may interact with medicines.
Turmeric and curcumin
Turmeric is a common food spice. Curcumin supplements are marketed widely, but evidence for treating disease remains limited and product quality varies. Supplements can interact with medicines and may not be appropriate for people with certain gallbladder, bleeding or liver problems.
Food use versus supplement doses
Using ginger or turmeric in food is different from taking concentrated capsules or extracts. A product labelled “natural” can still cause side effects or interact with prescription treatment.
Know the limit of a home remedy
Home remedies are best thought of as symptom-support tools for minor problems—not substitutes for antibiotics when indicated, emergency care, cancer treatment or management of serious chronic disease.
