In the manufacturing of incense toxic materials or processes can be involved.
Conventionally, incense sticks are rolled at the homes of workers. They are later dipped in essential oils, dried and packed in a factory.
In this process the essential oils are diluted with cheap chemicals (to keep the price low).
The result is a dipped incense which is strong and rich in chemicals, with a heavy fragrance that lingers for a long time and attaches itself to clothes and curtains.
Incense made by the masala method, means that the essential oils are included in the dough from which the sticks are rolled. This eliminates the need to dilute the essential oils with chemicals, and gives a fragrance which is far superior to that of dipped incense sticks. It also creates a healthier work environment for the incense makers.
