However, the probability of side effects does not extend to all users of the medication, and is generally limited to only a small section of users. It is necessary for all users to exercise a certain level of caution, as it may not be possible to be aware beforehand of the effects, until and unless the effects actually manifest. The effects, in terms of duration and intensity; may differ among individuals experiencing the effects, with most of the commonly occurring effects known to resolve naturally and quickly, with only few effects known to last longer and with stronger outcomes. Here is a list of commonly reported effects experienced by users of cinnamon, including use as an essential oil.

While this is effectively a remote possibility, as intake generally does not exceed certain levels, it cannot be entirely ruled out.

Blood thinning effect

In the event of inability to choose a safe strength, users are advised to dilute the oil to a level where its potency is sufficiently reduced to tolerable or safe levels.

Increased toxins due to coumarin levels

Various properties of cinnamon; such as antifungal, anticonvulsant, and neuroprotective properties are all attributed to coumarin, from the bark. While the organic chemical compound delivers the famed properties of cinnamon and the aroma associated with it, it also packs in certain possible adverse effects – including damage to the liver. Despite its proven source of antioxidants, the probable amount or strength of coumarin in the cinnamon oil is to be established conclusively. This will help prevent possible undesirable outcomes. Most users may be unaware that the actual strength of coumarin in different varieties differ, with some delivering levels that are considered as potent, while certain varieties may deliver lesser or moderate levels of the organic company.

When coumarin levels accumulate in the body as a result of heavy intake or long-term use, toxins build up, resulting in unwanted consequences.  It is essential to ensure that an upper limit is maintained, especially when cinnamon is used for an extended period. Ideally, intake levels are to be kept below 6 grams daily, to prevent any build-up of toxins. The time required for the natural flushing of toxins from the body is one week, and it is a good practice to leave a gap of one week, to rid the body of toxins and start afresh.

Reactions include skin irritation, and burning sensations, that are indicative of incompatibility. It is possible to follow precautions such as diluting the oil for users with sensitive skin, and when applied on areas of the body that have sensitive skin.

Impact of GMP on quality of cinnamon oil available commercially

The actual quality of cinnamon oil or other extracts of the bark may ultimately depend on the manner in which it is manufactured and packaged. Presently available in various forms, including as a tablet, there is every possibility of undesirable or unwanted side effects of cinnamon due to substandard manufacturing practices and inferior quality ingredients. The making of tablets often involves the use of silicon dioxide, and one of the reasons for possible undesirable outcomes is the use of this anticaking agent. Choosing a brand with a reputation of high standards and GMP helps avoid unwanted effects. Certain substances are known to have long term impact on health with continued use.

Impact of cinnamon on body temperature

Cinnamon, by virtue of its mechanism of action can result in possible increase in body temperature. This is especially true when the intake is heavy or strong.

This increase in temperature can result in tell-tale effects, including formation of boils under the tongue, or inside the mouth. Other indications of increased temperature include chaffed, cracked or dried lips. Users are also known to end up with pimples, apart from watery discharge from the eyes, as outlined earlier. Individuals on other OTC products or medications or essential oils that increase body heat, are not to combine therapy or treatment with cinnamon oil, as this could result in complications from increased body heat. When the body temperature increases beyond a certain threshold, then it may be necessary to look at other options to reduce the temperature. This may also have an impact on other functions or organs of the body, which may necessitate medication if the increase is high or beyond a particular level.
