In earlier days incense sticks were made with tree resins, aromatic herbs and plants. Slowly as the consumption increased usage of synthetic chemicals has been started. In today's market, it is very difficult to find incense sticks made with high-quality materials. Many of them are made with artificial fragrances and unsustainably harvested plants. The chemicals that are being used for the fragrance are toxic and they harm our health. Not only to our health but also to the environment, these chemicals are risky. They may cause even heart problems sometimes. So we should try to use quality material that is manufactured by standard companies only. Otherwise, our respiratory system will be in trouble.
We use ghee in havan. We should use original ghee only. But these days what ghee we are getting in the markets are contaminated with other ingredients. So the problem comes. We should purchase quality ghee only and in such case, we will not have any problem. It is better to perform Havan always in a well-ventilated area only.
