Tea tree also helps to relieve the pain, itching, and inflammation of insect bites.
That would not be recommended. It can't be easily predicted which constituents of each herb would "survive" the process and which constituents may be affected by the constituents of the other plant. In addition, if you make them separately, you can choose whatever ratio of herbs you want to mix. In the end, taking an extra step should allow you more flexibility.

Promising research for breast health. 2014 Iranian research published in the journal Nutrition and Cancer found that lavender oil kills breast cancer cells but leaves healthy cells unharmed. It’s important to note that this study was on cells in a petri dish, not on humans. The researchers concluded that: “L. angustifolia has cytotoxic and apoptotic effects in HeLa and MCF-7 cell lines, and apoptosis is proposed as the possible mechanism of action.”2
Dry the plant material. Drying reduces the amount of oil in each plant, but can greatly increase how much essential oil you make per batch. This is because you’ll be able to fit more material into each batch. Drying should be done slowly and away from direct sunlight.[5] Commercially grown plants such as lavender and peppermint may be allowed to dry in the field after cutting for a day or so.
Diffuse lemon for health. Diffuse lemon oil (see #2 above) to help kill airborne bacteria. Research carried out by Dr. Jean Valnet (co-author of the book The Practice of Aromatherapy: A Classic Compendium of Plant Medicines and Their Healing Properties) shows that diffused lemon oil can rapidly kill off the bacteria that causes meningococcal infections, typhoid fever, staph infections, pneumonia, diphtheria, and tuberculosis.
After asking the patients to record their headache severity and associated symptoms every 30 minutes for a total of 2 hours, researchers found that the difference between the controls and treated patients was statistically significant. From 129 headache attacks in the treatment group, 92 responded entirely or partially to lavender. In the control group, 32 out of 68 headache attacks responded to the placebo. (19)
Health benefits: This essential oil aids in digestion, increases perspiration and helps remove toxins from the body. It also helps to remove gases from the intestines and does not let them build up while acting as a purgative, curing spasms, and helping to treat arthritis and rheumatism by removing uric acid and other toxins from the body. Black pepper essential oil inhibits bacterial growth, fights premature aging, and neutralizes free radicals that damage the body in countless ways.
Another useful essential oil for digestion is peppermint. Research shows that peppermint oil works to provide rapid relief of IBS symptoms. In a 4-week, randomized, double-blind, placebo-controlled clinical trial, 72 patients with IBS received either peppermint oil or placebo. The peppermint group experienced a 40 percent reduction in total IBS symptoms after 4 weeks, which was superior to the 24 percent decrease of symptoms reported by the patients in the placebo group. After just 24 hours of using peppermint oil, the treatment group experienced a decrease in symptoms of 19.6 percent. (8)

Essential oils may help to reduce toxicity by promoting the detoxification of your home and body. These days, we are all inhaling and ingesting a number of chemicals and environmental toxins that can be dangerous for our health. Some work as mild diuretics, thereby increasing urine production and improving detoxification. And some oils aid digestion and promote the detoxification of toxins that buildup in the body. (18)

Studies have shown that essential oils effectively destroy several fungal, viral and bacterial pathogens, including methicillin-resistant Staphylococcus aureus, Helicobacter pylori and Candida albicans infections. Because antibiotic resistance is becoming such a major threat in modern health care, using these oils as a form of independent or combination therapy can help to fight bacterial infections in a safer and more natural way.  (4, 5)
