Are there any risks associated with the use of rose geranium essential oil?
Theessential oil of rose geranium has historically been used for its fragrant properties in the perfume industry. Today, it is increasingly incorporated into skin and hair cosmetic products. However, its inclusion may raise questions about the potential dangers it poses when used.
Overall, the essential oil of rose geranium exhibits a superb safety profile. Its likelihood of acute toxicity has been assessed as "low to very low".
Nevertheless, it can still pose problems in certain cases. Like all essential oils, when applied topically, it can cause irritation reactions. Indeed, the essential oil of rose geranium is rich in citronellol (45%), geraniol (6.5%) and linalool (3.8%), allergenic compounds that can be sensitising.
Precautions to take before using rose geranium essential oil.
A study has shown that this oil is not toxic at dilutions up to 5%. When applying to the skin, we therefore recommend diluting two to three drops of essential oil in a tablespoon of vegetable oil (1 to 3%) and not exceeding this dosage. As a precaution, avoid sensitive areas, such as around the eyes and open wounds. It is also advised to perform a skin test of the solution before applying it more generally by taking a few drops of the product, spreading it in the crook of the elbow or behind the ears, and waiting 24 hours to observe any potential skin reactions.
Pregnant women beyond their third month of pregnancy, breastfeeding women, and children over three months old can generally use the oil without any particular concerns.
For oral consumption, dilute one to two drops in 250g of food, to be taken no more than once a day. It should be noted that its oral use is not recommended for individuals undergoing allopathic treatment for diabetes. Furthermore, there may be potential drug interactions. Indeed, geraniol inhibits cytochrome 2B6, an enzyme involved in the metabolism of certain drugs, notably antimalarials, painkillers and anti-tumour drugs. If you are taking one or more of these types of medications, discuss it with your doctor.
At the slightest doubt, consult a health professional.
