Monoterpenes and compounds containing two isoprene units, which is ten carbon atoms and sixteen hydrogen atoms per molecule (C₁₀H₁₆) - molecular weight 136 amu for a hydrocarbon monterpene. There are an estimated 2,000 varieties of monoterpenes.

Monoterpenes are found in most essential oils: Grapefruit (92%), Angelica (80%), Frankincese (77%), Cypress (77%), Galbanum (75%), Pine (60%), Rose of Sharon (54%), Juniper (54%), Spruce (50%), Myrtle (37%), Hyssop (30%), and Peppermint (11%).

While offering a variety of healing properties, the most important ability of the monoterpenes is that they can reprogram miswritten information in the cellular memory (DNA) (restoring God's image, Genesis 1:26). With improper coding in cellular memory, cells malfunction and diseases result, including lethal ones, such as cancer.

Sesquiterpenes are compounds containing three isoprene units, which is fifteen carbons and twenty-four hydrogens per molecule (C₁₅H₂₄) - molecular weight 204 amu for a hydrocarbon sesquiterpene. There are more than 10,000 kinds of sesquiterpenes.

Sesquiterpenes are the principal constituents of Cedarwood (985), Vetiver (96%), Sandalwood (aloes) (95%), Patchouli (85%), Ginger (70%), Myrrh (60%), Spikenard (50%), and Black Pepper (47%). They are also found in Galbanum (4%) and Frankincense (8%).

Sesquiterpen molecules deliver oxygen molecules to cells, like hemoglobin does in the blood. Sesquiterpens can also erase or deprogram miswritten codes in cellular memory. Sesquiterpenes are thought to be especially effective in fighting cancer. The root problem with a cancer cell is that it contains misinformation, and sesquiterpenes can delete that garbled information. At the same time the oxygen carried by sesquiterpene molecules creates an environment where cancer cells can't reproduce. Hence, sesquiterpenes deliver cancer cells a double punch - one that disables their coded misbehavior and a second that stops their growth.
