Is the Candida Spit Test Accurate? : Exclusive Interview with Dr. Jeffrey McCombs

Ever wonder if the myths you hear about candida are really true?

In Part 2 of my interview with Dr. Jeffrey McCombs, we address some of the common myths around candida and determine what is true and what is not based on his clinical experience.

During the call, we talk about the “spit test” and it’s effectiveness, whether or not a white coating on the tongue is candida or not, as well as other aspects like should you eat sugar or not and if probiotics and fermented foods are always good for those with candida.

I think you’ll really enjoy this second half of the interview… I know I did!

Here are my notes on Part 2 of the interview with Dr. Jeffrey McCombs…

1. A diversion from the accepted candida norm…

This was a great interview for me, since in the past I have suffered from a candida infection caused by antibiotics and an experiment with a high fruit diet.

Some of the information that Dr. Jeffrey McCombs talks about I’ve very familiar with… other bits are a little divergent from common candida knowledge.

I’m actually not sure who’s right or wrong (in fact all views are in some way correct), but what I do know is that Dr. McCombs has some serious candida chops and has worked with patients in a clinic for many years.

This clinical experience – and proof of results – seems to trump any theory in my book, so I made sure I listened to all of his points before drawing any conclusions.

The two that were most awkward for me to hear were these…

(1) You can eat fruit on his plan.
(2) He’s not a huge supporter of fermented foods during a candida protocol.

I’m going to address the fruit here and then the fermented foods / probiotics a little further down in these notes.

As for the fruit…

Dr. McCombs, in his clinical experience, has not seen that eating fruit while on an anti-candida diet stymies results. This may be shocking to you, but there’s some logic to it.

Dr. McCombs is recommending a full approach that is the sum of its pieces. So for instance, if you were to just eat fruit and not do the other things, I would wonder how effective the treatment is. I’m sure Dr. McCombs would say, “not so effective.”

So when dealing with candida and all the rules that come with it, we have to keep in mind there are different shades of effective treatment that depend on what therapies are being used.

Just like you wouldn’t make an oil and vinegar dressing without vinegar, you wouldn’t carelessly eat fruit without the antifungal supplements he mentions in his entire protocol.

Just something to think about.

2. The connection between mucus and candida.

Dr. McCombs spends plenty of time in this second portion talking about the link between candida and mucus.

Simply, what he says is that if you’re eating foods that are causing mucus, or have inflammation in the gut that causes mucus to form, your chances of getting rid of candida are decreased.


Because the mucus covers the lining of the intestines (and the candida that is growing there) and makes it harder for your body to naturally regulate the infection or for any other therapy you’re taking – such as herbal medicines and foods – to be effective.

3. Caprylic acid not as effective as undecylenic acid.

According to Dr. McCombs, undecylenic acid is a more effective natural antifungal than the popularly prescribed caprylic acid. Undecylenic acid is derived from castor oil which is just as natural as caprylic acid which is derived from coconut (in most cases.)

He’s used this effectively in the clinic so there’s no reason to doubt his results.

My advice, if you have candida, is to get serious about a treatment and give it your best shot. If the treatment requires a certain supplement that you think may or may not work, suspend your judgement and let the treatment do the talking.

4. A die off reaction can cause inflammation and mucus.

A die off reaction from candida means the immune system is working hard to eliminate the infection.

Some people have said this may be a good sign and that healing is just around the corner.

Dr. McCombs says that this isn’t exactly true.

A die off reaction, while it may be a sign that something is working, can also cause inflammation which in turn creates mucus that can hinder the healing process.

Ultimately, what he feels is most important for eliminating candida is to control the amount of mucus forming foods you’re eating, take appropriate supplements, sweat, drink plenty of water and be patient.

His results seem to prove that this is at least pretty effective.

5. Probiotics increase inflammation which can stimulate an immune response.

This is an interesting concept that may explain something that Donna Gates said to me once.

She said some people with candida can’t start on probiotics or fermented foods – they just seem to react poorly.

What Dr. McCombs mentions in this interview about probiotics being a little pro-inflammatory in the gut – on first introduction – could completely explain why some people can’t use them when they’re trying to get rid of their candida at first.

Dr. McCombs doesn’t completely write off probiotics though, a patient using his therapy can take them later on in the process – they also can eat fermented foods then as well.

5. Spit the “spit test” in the garbage.

There’s a popular home test that is talked about frequently when the topic of candida comes up.

On the street it’s called the “spit test,” and it goes like this…

In the morning, you wake up and spit into a cup of water. You wait about 30-60 minutes and take a look at what you have in your cup.

If the spit has “legs,” then supposedly you have have candida.

The only problem with this test, is that it’s not accurate at all.

Not even close.

The legs can be saliva, mucus or even other bacteria.

Not the best (or reliable) way to determine if you have a potentially harmful fungal infection.

You can pretty much spit this test in the garbage and use the testing protocol that Dr. McCombs talks about in Part 1 – at least if you’re serious about addressing your health challenges in the most effective way.

6. The truth about the tongue.

I’m glad I could finally get some more support on my theory that the coating on your tongue in the morning is not, in fact, candida, but just what naturally occurs on your tongue in the morning. It’s likely a mixture of bacteria and mucus that have accumulated overnight (it could in fact be some yeast as well, but not any indication of a real candida infection.)

There’s a natural health rumor that goes around on the Web that says if you wake up in the morning with a coating on your tongue, it’s a sure sign you have candida.

It’s not exactly false, but it’s pretty close to it.

You can get white on your tongue and it can be candida, but…

The real white “coating” on the tongue, that implies you have a vicious candida infection, is called thrush… and it doesn’t look like a grayish-white coating. It looks like real fungus growing on your tongue.

I’ll save you the images (or you can search yourself.)

So if you’re looking at your tongue in the morning and think that since a friend told you that it looked a little white that you may have candida, I’m going to let you down lightly… chances are your tongue isn’t going to be a good indicator.

You may have candida, but your tongue won’t be the best sign.

On the other hand, if you have fungus on your tongue – real, white spots or patches – then, yes, you have it bad.

I want to know your thoughts: Have you done the spit test before?
