It has been used since 3,600 BC. Incense is a traditional and universal practice in almost all Pujas, Prayers, and other forms of worship.
As part of the daily ritual worship within the Hindu tradition, Incense is offered to God in His deity forms, such as Krishna and Rama. This practice is still common place throughout modern-day India and Hindus all around the world by using Incense and offerings each day by temple priests or by those with an altar in their homes and businesses.
Traditionally, the Benzoin resin and Gugal resin, from a tree similar to Myrrh, were used as Incense in ancient India. These resins would be spilled over embers which would give out perfumed smoke. However, the majority of the modern-day Incense of India is mostly of a Chemical Base rather than the Natural Ingredients.
