Herbal Incense Safety: What's The Real Story?

is herbal incense safe

Burning incense is a practice with deep roots in many cultures and traditions. Incense is made from aromatic substances and a heat source, with the heat releasing the scent. While incense is often used for hygienic, spiritual, and health purposes, there are concerns about its impact on health. Recent research suggests that incense smoke contains particulate matter, including carcinogens and irritants, which can be inhaled and lead to respiratory issues and potentially cause cancer. However, it is important to note that the specific mechanisms and health risks associated with incense burning require further investigation, especially in the case of human studies. The type of incense and the burning conditions can also impact the emission of particulate matter, with pure pressed raw ingredients and higher metallic content resulting in reduced harmful emissions. Additionally, common-sense precautions, such as ventilation and avoiding direct exposure, can help minimize potential risks.

Incense smoke contains carcinogens and irritants

Burning incense produces a significant amount of smoke, which contains particulate matter that can be easily inhaled. This particulate matter includes a variety of toxic and irritant compounds, such as polycyclic aromatic hydrocarbons (PAHs), benzene, and carbonyls, which are known carcinogens. These carcinogens are similar to those found in tobacco smoke and have been linked to an increased risk of respiratory diseases, including asthma and respiratory tract carcinomas.

The smoke released from burning incense can trigger asthma and has been associated with the development of respiratory allergies. It is also linked to an increased risk of heart disease. Furthermore, a 2020 study found that long-term exposure to incense smoke may negatively impact brain health in older adults over 65 years of age, leading to potential issues with cognitive performance and brain connectivity.

While the potential health risks of incense smoke are concerning, it is important to note that the specific mechanisms behind these associations are not yet fully understood. Further research is needed to establish causal relationships and determine the precise health effects of incense smoke exposure.

The type of incense and the method of burning can also impact the amount and toxicity of the smoke produced. For example, pure pressed raw or powdered ingredients tend to produce less smoke and are generally safer, while ropes infused with incense may have a higher base-to-essence ratio, contributing to increased smoke production.

Incense smoke and respiratory health

Incense smoke contains natural and unnatural ingredients that create small, inhalable particulate matter. A 2021 study confirmed that some of this particulate matter is carcinogenic, meaning it could cause cancer. There is also an association between higher cancer risk and incense use. However, it is important to note that no large-scale studies have conclusively shown that moderate incense use at home releases enough chemicals to significantly affect a person's risk of cancer.

Particulate matter in incense smoke contains carcinogens and irritants, which could lead to respiratory diseases such as asthma. Burning incense may trigger asthma and has been associated with the development of respiratory allergies. Studies suggest that incense smoke can also trigger chronic inflammation in the body, which can affect heart tissues and contribute to overall inflammation.

The type of incense and burning conditions can impact the emission of harmful particulate matter. For example, pure pressed raw or powdered ingredients, as commonly found in Tibetan and Japanese incense sticks, tend to produce less smoke and are considered safer. On the other hand, ropes infused with incense, typically Indian, tend to have a high ratio of base to essence, resulting in excessive smoke production.

To minimise potential health risks, it is recommended to take precautions when burning incense. This includes regularly ventilating the area, ensuring adequate spacing between individuals and the incense smoke, and choosing health-friendly incense products. Additionally, it is important to weigh the potential risks against the benefits, as incense ingredients have been scientifically proven to offer relaxation, improved mood, and various health benefits.

Incense ingredients and their benefits

Incense has been used across various cultures for millennia for hygienic, spiritual, and medicinal purposes. While some ingredients in incense have been linked to certain health benefits, other ingredients have been flagged as potentially harmful.

Incense ingredients can be broadly categorized into dried herbs, seeds, and berries, and resins. Common dried herbs, seeds, and berries used in incense include juniper, hawthorn berries, pine and fir cones, pine and fir needles, yarrow leaves, rose petals, oregano, thyme, cedar leaves, desert sage, calendula flowers, mugwort, moss, lichen, lavender flowers, lomatium seeds, lovage seeds, nutmeg, and cloves. Common resins used in incense include fir and pine resins, cherry sap, cottonwood leaf buds, rosemary, ceanothus red root leaves, garden sage leaves, hops flowers, and camphor.

Some of the potential benefits of incense ingredients include:

  • Cleansing the air of disease: Incense has been used for centuries to purify the air and prevent the spread of disease.
  • Creating a sacred space: Burning incense is often used to create a spiritual or sacred atmosphere and is commonly used in religious ceremonies and rituals.
  • Evoking memories and emotions: Certain scents in incense can trigger powerful emotional responses and evoke memories.
  • Reducing tension and stress: Incense has been known to promote relaxation and reduce stress and tension.
  • Aiding in meditation: The aromatic properties of incense can enhance focus and concentration during meditation.
  • Healing the lungs: Some herbs used in incense, such as sacred True Tinder Fungus (Chaga) and sacred Sweetgrass, are believed to have lung-healing properties.
  • Offering a "high": Synthetic cannabinoids added to herbal blends, such as "Spice," can produce a marijuana-like "high." However, it is important to note that these synthetic compounds have been linked to negative health effects and are not considered safe.

It is important to note that while incense has been used traditionally for various purposes, recent research has raised concerns about the potential health risks associated with burning incense. Studies have found correlations between incense use and increased risks of respiratory issues, asthma, heart disease, and cancer. Therefore, it is essential to exercise caution and ensure proper ventilation when using incense.

Natural vs synthetic incense

Natural incense is made from raw materials such as real wood, resins, herbs, flowers, and spices. Some natural incense also contains sacred herbs like True Tinder Fungus, Sweetgrass, and Sage, which are considered to have medicinal properties. For example, some herbs are intended to heal the lungs, and North American Indian recipes for clearing the lungs involve smoking herbs in pipes or adding them to a central fire.

On the other hand, synthetic incense is made from artificial fragrances, some of which are derived from petroleum, the cheapest raw material. While these fragrances may smell similar to their natural counterparts, they are chemically distinct. For example, while vanillin is chemically identical to the vanillin found in vanilla pods, vanilla pods contain hundreds of other chemicals that lend complexity to the scent.

Natural incense is often handcrafted and made in small batches, with ingredients that are ground, dipped in resin, rolled, and sun-dried. Some natural incense is also packaged with eco-friendly, handmade paper. However, natural incense can produce a large amount of smoke, which can be an irritant and cause respiratory issues, especially with long-term use. A 2021 study found that incense smoke contains carcinogens, which could increase the risk of developing cancer.

Synthetic incense, meanwhile, is often mass-produced and may contain toxic ingredients, such as petroleum-based fragrances, which can be inhaled when burning the incense. The incidence of adverse reactions is higher with synthetic incense, and the smell is often described as foul.

Overall, while natural incense may be more expensive and produce more smoke, it is generally considered safer and more pleasant-smelling than synthetic incense. However, it is important to note that both natural and synthetic incense can contain carcinogens and irritants, and proper ventilation is recommended when burning any type of incense.

Safe ways to burn incense

Burning incense is a popular way to add fragrance to your home, but it's important to use it safely. Here are some tips to burn incense safely:

Use proper incense holders

Incense holders or stands are important to keep the sticks upright. When shopping for an incense holder, look for one made of heat-resistant materials like crystal, metal, or ceramic. These materials usually don't get as hot and are safer to use. Avoid using wooden holders unless they are made from heat-resistant wood or treated properly to resist fire.

Burn incense on a heat-resistant surface

Always burn incense on a heat-resistant surface to prevent fire hazards. Never burn incense on flammable surfaces such as wood or fabric.

Ensure proper ventilation

Ventilation is essential when burning incense. Burning incense in a poorly ventilated room can cause the concentration of smoke to build up, which can be a health hazard. Make sure to burn incense in a well-ventilated area and consider airing out your rooms regularly.

Keep domestic pets in mind

While enjoying the benefits of incense, it is important to consider the health of domestic pets. Keep them as far away from incense smoke as possible, as birds are especially sensitive to smoke.

Extinguish incense properly

To extinguish incense, place the burning end in a bowl of sand or water. Avoid blowing it out like a candle, as incense sticks have far more embers than candles, and blowing them out can disperse burning embers. Once the incense is fully extinguished, you can dispose of it in the trash.

Choose incense with pure and pressed raw ingredients

When selecting incense, opt for those with pure pressed raw or powdered ingredients, as they tend to produce less smoke and are generally safer. Large-diameter Tibetan sticks, for example, can be burned for a shorter duration or broken into smaller sizes to reduce smoke emission.
