Incense smoke contains N-nitroso compounds, which are nervous system carcinogens
Incense is an aromatic biotic material that releases fragrant smoke when burnt. It is composed of aromatic plant materials, often combined with essential oils. The smoke released from burning incense contains particulate matter (PM), gas products, and other organic compounds.
Incense smoke contains various N-nitroso compounds, which are nervous system carcinogens. Preston-Martin et al. studied the mothers of 209 young brain tumour patients and 209 control subjects. They found an increased risk of brain tumours associated with exposure to nitrosamine-containing substances, including burning incense. However, conflicting data exists regarding the link between incense smoke and cancer. Some studies have shown no association between incense smoke and cancer, with smoking being the most significant risk factor for lung cancer in Hong Kong.
The particulate matter in incense smoke has been linked to respiratory issues and increased cancer risk. It produces particulates greater than 45 mg/g burned, compared to 10 mg/g burned for cigarettes. The gas products from burning incense include CO, CO2, NO2, and SO2. It also releases volatile organic compounds, such as benzene, toluene, and xylenes, as well as aldehydes and polycyclic aromatic hydrocarbons (PAHs).
The air pollution caused by incense burning in and around temples has been documented to have harmful effects on health, including respiratory system dysfunction. Burning incense may also contribute to overall inflammation and affect heart tissues. A 2020 study found that it may cause issues with brain health in older adults, including delays in cognitive performance and decreased brain connectivity.
To reduce potential health risks, it is recommended to limit incense use and exposure to its smoke. Opening windows during or after burning incense can help reduce exposure. Exploring alternatives to incense is also an option for those concerned about the risks.

Incense smoke patterns are used in an ancient practice called Libanomancy to predict future events
Incense is an aromatic biotic material that releases fragrant smoke when burnt. The term refers to both the material and the aroma. Incense is used for a variety of purposes, including aesthetic reasons, religious worship, aromatherapy, and meditation.
Libanomancy is believed to have originated in ancient Mesopotamia during the Old Babylonian period (2000 BCE to 1600 BCE), and was later popularised in ancient China, India, and Europe via the Middle East. It was particularly prevalent during the Renaissance, when people were keen to explore methods of divining the future. The practice involves burning incense on a charcoal disc or in a censer, and then interpreting the smoke patterns that form. Alternatively, a piece of paper with an intention written on it can be burned with incense, and the resulting smoke pattern interpreted.
To perform Libanomancy effectively, it is recommended to use natural and organic incense made with herbs, essential oils, resins, and flowers. The incense should be burned in a quiet room without drafts or airflow to ensure clear smoke signals. Practitioners should also be calm and open-minded, focusing on their questions and interpreting the smoke patterns accordingly.

Incense smoke is used in religious worship, aromatherapy, meditation, and ceremonies
Incense is an aromatic biotic material that releases fragrant smoke when burnt. The smoke released from burning incense is called incense smoke. Incense smoke is used in a variety of settings, including religious worship, aromatherapy, meditation, and ceremonies.
Religious Worship
Incense smoke is widely used in religious worship across various traditions. In traditional Chinese religion, for example, incense-stick burning is a common everyday practice, with different types of sticks used for different purposes or festive days. In some states, such as Taiwan, Singapore, and Malaysia, large pillar-like dragon incense sticks are burned outdoors during the Ghost Festival. In Christianity, censers, or incense burners, made of precious metals and provided with chains for hanging, have been used since the 4th century, and the rite of swinging the censer is practiced in many rituals.
In pre-Columbian Mexico and Peru, incense burners were made of terra-cotta or gold, and in pre-Hellenistic Egypt and among ancient Jews, incense was burned in golden bowls or cauldrons placed on or near the altar or outside the temple. The use of incense in these traditions often carries symbolic meanings, such as signifying purification, symbolizing prayer, or serving as an offering to the sacred or celestial realm.
Aromatherapy and Meditation
Incense is also used in aromatherapy and meditation practices. Certain scents, such as lavender and sage, are believed to promote relaxation and enhance the meditation experience. Research suggests that scent can be a powerful cue for triggering memories, and an incense scent that evokes pleasant memories may contribute to feelings of relaxation. However, it is important to note that there are potential health risks associated with inhaling incense smoke, and it is recommended to practice incense meditation only in well-ventilated areas.
Ceremonies
Incense smoke is further utilized in various ceremonies and rituals. In Japan, for instance, the censer (kōdan), a vessel with a perforated cover and carried by chains, is employed in Buddhist and Shintō rituals. The smoke and aromas produced by incense burners have been believed to induce a mystic exaltation and contribute to well-being. In some cultures, incense is also used as a protective device, believed to ward off evil or demonic spirits.

Incense mixtures must be pulverised with similarly sized particulates to avoid uneven burning
Incense is an aromatic biotic material that releases fragrant smoke when burnt. The term "incense" refers to both the material and the aroma it produces. Incense has been used for various purposes throughout history, including aesthetic, religious, and ceremonial reasons, as well as for aromatherapy, meditation, and even as a deodorant or insect repellent.
The process of creating incense involves combining aromatic plant materials with essential oils. The specific ingredients and forms of incense vary across different cultures and have evolved with technological advancements. However, the importance of consistent particulate size in incense mixtures is universal.
To create incense sticks, thin sticks are separated and dipped into a tray of incense powder containing fragrance materials and, occasionally, a plant-based binder. This process is repeated several times, with the incense powder being tossed and piled over the sticks to achieve a thickness of 2-4 millimetres. The coated incense is then left to dry in the open air.
The incense mixture must be well pulverized with similarly sized particulates. Uneven or large particulates can result in uneven burning and inconsistent aroma production. This is because incense with uneven particulates may burn too quickly or slowly, or produce an inconsistent fragrance. Therefore, it is crucial to ensure that the incense mixture has a uniform consistency and particulate size to achieve optimal burning and fragrance release.
Additionally, the density of the incense mixture is crucial. Adding too much water or over-compressing the mixture during preparation can lead to uneven air distribution and undesirable density. This, in turn, can cause the incense to burn unevenly. Therefore, it is essential to control the amount of water and compression during the mixing process to ensure a consistent and desirable burning experience.
