Paraffin candles are typically made from petroleum byproducts. When burned, they release potentially harmful chemicals like benzene and toluene, both of which are known carcinogens. Inhaling these fumes can irritate the respiratory system and may contribute to air pollution indoors. Natural ghee lamps on the other hand are typically made from clarified butter and provide a cleaner and healthier burn. They do not emit harmful toxins, making them a safer choice for indoor air quality.
