We now recognize that dandruff is induced by means of a fungus that lives and feeds on the human scalp—the two principal implications being, first, how “alarming” it is that a bogus concept can remain in the medical literature unchallenged for a century notwithstanding proof to the opposite;
But, you don’t recognise if it really works for dandruff, until you positioned it to the take a look at.
one hundred twenty-six women and men randomized to each day use of a “5% tea tree oil shampoo or placebo” for a month. The placebo labored a bit bit, reducing dandruff severity with the aid of about 10%, however the tea tree oil shampoo worked higher—approximately a 40% drop.Looks like extra than 40% from the image, however that’s due to the fact they misleadingly commenced the Y-axis at -60.
This is a classic deception featured within bankruptcy 5 of the 1954 conventional How to Lie with Statistics. The graph need to truly seem like this, which makes the impact less amazing, however it changed into nevertheless statistically vast.“[O]nly one patient [in the tea tree oil group] really finished a entire response,” although one within the placebo group did as properly.
Thus, it appears that the “tea tree oil shampoo would require ongoing utility for control of dandruff.” Speaking of fungus, what about tea tree oil inside the remedy of athlete’s foot?So, about one hundred sufferers randomized into one of three companies, a ten% tea tree oil cream, tinactin (an antifungal drug), or a placebo cream.
A month later, the fungus became worn out within 85% of the drug organization, but most effective approximately 1 / 4 of the placebo and tea tree oil organizations. This is somewhat unexpected, on account that tea tree oil can kill off the fungus in a petri dish—but, seemingly, now not on toes.That strikes a chord in my memory of a number of the oral health statistics on tea tree oil.
No effect.
So, if tea tree oil doesn’t impact the amount of plaque, presumably it wouldn’t assist with gingivitis, the gum inflammation that’s because of plaque buildup. But, no;here’s the twist.
True, no reduction in plaque with a 2.5% tea tree oil gel—but “massive reduction” in gingivitis scores. Since decreased gum irritation occurred with out a decrease within plaque, it seemed to simply be assisting greater from an anti inflammatory in place of antimicrobial mechanism.Might the equal component be taking place here?
Yeah, from a mycological treatment perspective—a fungus therapy point of view—tea tree oil didn’t surely do any better than placebo.So, “[t]his may be the idea for the famous use of tea tree oil in the remedy of [athlete’s foot].” But, humans should understand that it’s just symptomatic comfort, and they’re not always disposing of the underlying purpose.
Of direction, perhaps they didn’t use a sturdy sufficient awareness. And, indeed, if you go together with no longer a ten% cream, however up to twenty-five or 50%, you can get “mycological remedy fee[s]” above that of placebo, however still no longer as accurate as the drug.And, at those excessive concentrations, a number of the sufferers making use of tea tree oil “advanced moderate to excessive dermatitis”—they broke out within a rash.
