*Carcinogenic oils : There are some essential oils that are carcinogenic and have already been banned from use in aromatherapy as well as for internal usage. The oils in question are calamus oil (contains asorone), and all oils that contain high amounts of safrole like sassafras oil which is also found in yellow and brown camphor.Other compounds found in essential oils that may be carcinogenic is methyl chavicol, which is found in basil oil. This statement does not make basil a dangerous oil, but care should be taken to select the basil oil with the highest linalool content and lowest methyl chavicol content.It must however be pointed out that studies showed these oils as carcinogenic when applied daily in high concentration over a period of months.

*Using essential oils when you have cancer : If you have cancer there are some points to keep in mind when using essential oils and aromatherapy:Keep massage light, and avoid deep massage over muscles as well as near the lymph glands.Do not massage areas that have been irradiated.Do not massage areas that have skin cancers.Various writers on health, cancer and medical conditions have compiled lists of oils which should not be used when you have cancer.

* [[Frankincense]] Essential Oil Targets Cancer Cells : A study in the journal BioMed Central journal of Complementary and Alternative Medicine, March 2009, titled: "Frankincense oil derived from Boswellia carteri induces tumor cell specific cytotoxicity" concludes with: "Frankincense oil appears to distinguish cancerous from normal bladder cells and suppress cancer cell viability. Microarray and bioinformatics analysis proposed multiple pathways that can be activated by frankincense oil to induce bladder cancer cell death. Frankincense oil might represent an alternative intravesical agent for bladder cancer treatment." ...while a bit technical, this is very, very promising -- essentially saying that this easily obtained, inexpensive, NON-TOXIC natural compound can eradicate cancer cells without harming normal, healthy cells in the same organ. Frankincense has a long, long history of medicinal use, and searching for 'frankincense cancer' produces 30 results just for this material. If choosing an essential oil of Frankincense, the 'carteri' species has been the subject of most research, with cold-process Carbon Dioxide distilled oils considered the most therapeutic (seek CO2 or SCO2 distilled oils or extracts, as offered by Ananda here).
