1. Understand the ingredients and functions of health care products: spread information about ingredients, characteristics and efficacy of health care products to the elderly, and tell them the scientific value, safety and reliability of ingredients.
2. Analyze the reliability of health care products: look for professional reports or studies that can prove the effect of health care products, and tell the elderly whether the company established is qualified and has been approved by relevant departments.
3. Send safety information to the elderly: tell the elderly how to use health care products and possible adverse side effects. It is necessary to help the elderly to look at health care products scientifically and correctly distinguish between health care products and medicines.
4. Guiding drug purchase: Some elderly people lack a correct understanding of drugs and don't know how to choose and use drugs correctly. We need to explain to them the different kinds and functions of drugs and how to use them correctly.
5. Anti-fraud publicity: the elderly need to be vigilant and consider the authenticity and reliability of the advertisements they see from multiple angles, such as checking the qualifications and research certificates provided by advertisers to find out whether there is authoritative certification.
In short, we should keep understanding and patience in the communication with the elderly, seek their questions about the purchase of health care products and drugs, and provide relevant scientific information. If you have other questions, you should consult a professional doctor or pharmacist to obtain accurate and authoritative information through legal channels.
