Natural Lice Prevention and Lice Treatment

Permethrin and Pyrethrin: Losing the battle

The insecticides that have been the over-the-counter treatments of choice for head lice eradication are permethrin and pyrethrin, commonly known as Nix rinse and Rid shampoo. These products work by penetrating, then changing the chemistry of the nerve cells of lice causing eventual paralysis and death. They have been effective for years until the past decade or so, when certain genetic mutations started appearing randomly in lice, decreasing their susceptibility to this treatment.

So are we destined to be overtaken by lice or are there other options that may be as, if not more, effective and potentially much healthier?
Can Nature Come to the Rescue? Definitely!

It may seem as though all of this talk of super lice is bad news for the school-aged, lice-susceptible crowd, but I don’t think we need to be concerned. Personally, the side effects of the chemical insecticides under question scare the heck out of me anyway, so I would not likely use them on myself or my child anyway. Remember, the skin is our largest organ and anything that comes into contact with it is taken up directly by the body. So if we put toxins on our outsides, they will, no doubt, make it to our insides, burdening our liver and wreaking havoc on our hormone balance, at the very least.

Just because the mainstream chemical-based treatments are losing effectiveness, our hands are hardly tied when it comes to our battle against lice. In fact, this is an ideal time to research safer and more natural options (as I presume you’re doing right now!) that will eliminate the threat of both regular and “super” lice. As usual, nature doesn’t leave us high and dry, as there are many natural options. Let’s take a look at what’s been proven effective to date when it comes to essential-oil-based lice treatments.

The Natural Lice Killers: Pure Essential Oils

Essential oils are the liquids of a plant that are extracted either through steam distillation or cold pressing. Considered to make up a sort of immune system of the plant, these oils alter their chemical composition on a constant basis in order to help the plant adapt to and survive the changing environment. A few of the specific purposes of an essential oil when it’s still inside the plant are: antibacterial and antifungal activity, deterrence of insects and other animals, and prevention of competing vegetation from growing nearby.

Essential oils are rich in what are called monoterpenes, chemical compounds with various beneficial characteristics including, in the case of tea tree oil, insecticidal properties. In fact, the two major constituents of tea tree oil, 1,8-cineole and terpinen-4-ol, have demonstrated anticholinesterase activity, which is similar to that of over-the-counter chemical insecticidal lice treatments.

That all sounds great, but if you’re like me, you want solid proof that something works before you try it on yourself, or more importantly, your children. I’m happy to say there is plenty of scientific proof that tea tree oil does, in fact, destroy lice. Consider the following:

One 2012 study examined the efficacy of two natural substances: tea tree (Melaleuca alternifolia) oil and nerolidol (3,7,11-trimethyl-1,6,10-dodecatrien-3-ol) against lice and and nits (eggs). At a 1% concentration, tea tree oil was found to kill 100% of head lice within 30 minutes of application. Twice that concentration (2%) of tea tree oil resulted in the failure of 50% of the eggs to hatch after 4 days.

Another study completed in 2010 compared the efficacy of tea tree oil and lavender oil, pyrethrins and piperonyl butoxide, and a “suffocation” product for the treatment of head lice in school children. Impressively, 41 of 42 (97.6%) of the tea tree oil/lavender oil treatment group were louse-free one day after the final application, whereas only 10 of 40 (25%) from the chemical insecticide group were free from lice after the last treatment.

One small study of 119 children in Israel, aged 6-14 years, found that a natural product containing coconut oil, anise oil and ylang ylang oil, applied to hair three times at five-day intervals, was as successful the chemical insecticide used by the control group. Both had a 92% success rate in the eradication of lice and no significant side effects.

So you can see that tea tree oil, although probably the most popular essential oil for use against lice, is not the only one that can be effective. Lavender, Ylang Ylang, even Rosemary essential oils can induce similar results. And the best part of this treatment is the fact that the essential oils are also very healing. So any irritation that you may experience as a result of a lice infestation will likely be subdued by using these amazing oils.

Now that we’ve established that essential oils are a safe and effective alternative to chemical insecticides for lice eradication, let’s discuss how exactly to best use these oils for treatment and prevention of lice.

How to Use Essential OIls to Prevent or Treat Head Lice

First and foremost, be sure to purchase a fine-toothed lice comb to comb through the infested hair daily. Soak the comb in rubbing alcohol between uses. Next, use one or more of the following methods for treatment and/or prevention:

Use this oil in a travel spray bottle to spray on hair and scalp prior to and following exposure to lice.

Apply this spray to the scalp just prior to bedtime and leave it in overnight. In the morning comb out dead lice and nits.


Make your own, or go here to buy some.  It’s cheaper than RID at the store – which will run you about $20 and is full of toxins. 

Diagnosed autism linked to maternal grandmother’s smoking in pregnancy

Diagnosed autism linked to maternal grandmother’s smoking in pregnancy

Scientists have looked at all 14,500 participants in Children of the 90s and found that if a girl’s maternal grandmother smoked during pregnancy, the girl is 67 percent more likely to display certain traits linked to autism, such as poor social communication skills and repetitive behaviors.

Researchers found that if the maternal grandmother smoked, this increased by 53% the risk of her grandchildren having a diagnosed autism spectrum disorder (ASD).

Scientists from the University of Bristol have looked at all 14,500 participants in Children of the 90s and found that if a girl’s maternal grandmother smoked during pregnancy, the girl is 67% more likely to display certain traits linked to autism, such as poor social communication skills and repetitive behaviours.

The team also found that if the maternal grandmother smoked, this increased by 53% the risk of her grandchildren having a diagnosed autism spectrum disorder (ASD).

These discoveries suggest that if a female is exposed to cigarette smoke while she is still in the womb, it could affect the developing eggs — causing changes that may eventually affect the development of her own children. Further research is now needed to find out what these molecular changes might be, and to see whether the same associations are present in other groups of people.

Unlike the analysis of autistic traits, which was based on over 7,000 participants, the 177 diagnosed with ASD were too few to analyse grandsons and granddaughters separately.

The discovery, published today in Scientific Reports, is part of an ongoing, long-term study of the effects of maternal and paternal grandmother’s smoking in pregnancy on the development of their grandchildren, who are all part of Children of the 90s. By using detailed information collected over many years on multiple factors that may affect children’s health and development, the researchers were able to rule out other potential explanations for their results.

The incidence of ASD has increased in recent years, and while some of this increase is undoubtedly down to improved diagnosis, changes in environment or lifestyle are also likely to play a role. The researchers also stress that many different factors, including genetic variation, are believed to affect an individual’s chances of developing ASD.

Past studies of maternal smoking in pregnancy and ASD in children have been inconclusive. Going back a generation has revealed an intergenerational effect, which interestingly is most clear cut when the mother herself did not smoke in pregnancy.

The reasons for this are not entirely clear but Professor Marcus Pembrey, one of the paper’s authors, says: ‘In terms of mechanisms, there are two broad possibilities. There is DNA damage that is transmitted to the grandchildren or there is some adaptive response to the smoking that leaves the grandchild more vulnerable to ASD. We have no explanation for the sex difference, although we have previously found that grand-maternal smoking is associated with different growth patterns in grandsons and granddaughters.

‘More specifically, we know smoking can damage the DNA of mitochondria — the numerous “power-packs” contained in every cell, and mitochondria are only transmitted to the next generation via the mother’s egg. The initial mitochondrial DNA mutations often have no overt effect in the mother herself, but the impact can increase when transmitted to her own children.’

Professor Jean Golding, another author, added: ‘We already know that protecting a baby from tobacco smoke is one of the best things a woman can do to give her child a healthy start in life. Now we’ve found that not smoking during pregnancy could also give their future grandchildren a better start too. We have started studying the next generation of participants (COCO90s), so eventually we will be able to see if the effect carries down from the great-grandparents to their great-grandchildren too.’

Dr Dheeraj Rai, another author, added: ‘We still do not know why many children develop autism and behaviours linked to it. The associations we observe raise intriguing issues on possible transgenerational influences in autism. Future research will help understand the meaning and mechanisms behind these findings. The National Autistic Society website contains a wealth of information about autism and details on how and where to seek advice.’

Alycia Halladay, PhD, chief science officer at the Autism Science Foundation (USA), said: ‘To date, research into the causes of autism has been limited to studying maternal or paternal exposures during pregnancy. By utilizing a birth cohort in the United Kingdom [Children of the 90s], scientists are able to go back a generation to examine the role of grandparental exposures, presumably through germ line mutations and epigenetic modifications. Hopefully, grandparental exposures will continue to be investigated to better understand this mechanism.’
