Hello @memamun ,hope you are having a good day.Thank you for sharing about ancient medicine in your country. It's interesting to learn how people used natural remedies long ago. I agree that beliefs can affect health, and mental well being is important for getting better. Using plants like leaves and roots for medicine sounds helpful. Your idea about using clay pots and alum to purify water is smart for staying healthy. Thanks for sharing🤗🌸🌺.
