The story goes like this…
Dr. Heidi Yellen was curious about the instructions in the Torah/Old Testament (Deuteronomy 22:11), which states, “do not wear clothes of wool and linen woven together.”
Could there be a logical explanation for this?
In 2003, she ran a study to examine the frequencies of different fabric. She used a machine called the “Ag-Environ machine” which had been used to measure the “signature frequency” output of plants and the human body. The machine’s inventor, Bob Graham, found that the human body had different frequencies based on its level of health. The healthier the body, the higher the frequency.
A healthy human body registered a frequency of 100, but a very diseased body had a frequency of 15.
Yellen’s study reported the following “signature frequencies” different fabric:
- Linen: 5,000
- Wool: 5,000
- Mixed linen and wool: 0… it appears that the frequencies cancel each other out. Perhaps this accounts for the ancient instructions not to mix these fabrics.
- Organic cotton – 100
- Cotton – 70
- Silk – 15
- Polyester – 15
- Rayon – 15
Pretty interesting, right?
Note that I began this article by saying: “the story goes” as I can’t track down the original study. This is the most informational document I’ve found, but it’s not a primary source.
While I don’t have as much details as I’d like regarding this elusive study, the information reinforces what I’ve intuitively felt about natural fiber vs. synthetic fiber clothing. Even before I heightened my awareness around the materials/products I used on my body, I gravitated towards natural fibers like cashmere and cotton. I felt a cloying, restrictive quality to fabrics like rayon and polyester, even if the clothes were loose-fitting.
When I read about Yellen’s research, I remembered when I was 18 and healing my autoimmune illness with an intensive nutritional protocol. I was nearly bedridden, and for months, all my energy went towards nursing myself back to health through research and the GAPS nutritional protocol.
At this time, my sensitivity to clothing heightened. I found myself with intense craving for certain clothing, and repulsion towards other clothes. For these months, I wore only loose linen shirts, cotton shorts, and a cotton bathrobe.
What does “frequency” mean?
Energy, light, and matter all exist on a vibrational continuum. A tiny portion of this continuum is the electromagnetic spectrum, and of that spectrum, a tiny portion is visible light.
All physical matter consists of vibrating atoms, which we call “energy” or “frequency.” Physical matter — including your body, a table, or a computer — only seems solid due to the vibration of the atoms. Matter is 99% empty space and only feels solid due to the vibration of atoms.
Throughout millennium, human beings have been aware of other energy fields/frequencies which aren’t visible to the naked eye, or measurable by current scientific devices. The human body —functioning optimally — is a highly attuned extrasensory instrument, far more perceptive to spectrums of energy than our most advanced technology.
(Side note: that’s why I educate about the dangers of the transhumanism agenda, because the end-game is the destruction of the extra-sensory spiritual perceptions of the human body. When a human being is divorced from their intuition and spiritual energies, they become a soulless, compliant slave.)
When we understand that all physical matter has different vibrational qualities, we can ask, “Is it possible that these different vibrations have positive or negative effects on our health?”
I believe so.
I think it’s possible the high frequencies of fabrics like linen and wool bring energy to the human body, and support the body’s healing process.

Other Problems with Synthetic Fabrics
When we wear fabrics like rayon, nylon, and polyester, we’re essentially wearing plastic. These fabrics are shown to shed microplastics into the water supply when laundered.
Further, it raises the question: can these microplastics be absorbed by the skin? Are the other toxic chemicals used in synthetic fabrics be absorbed through the skin? And can working out in plastic fabric (i.e. polyester yoga pants) cause increased exposure to the fabric’s chemicals and microplastics, due to increased moisture and heat?
Additionally, some athleisure clothing (including Nike, Athlete, and The North Face) is shown to contain BPA, a toxic chemical used in plastic manufacturing. BPA has been found in polyester/spandex fabric blends.
Chemical testing of yoga pants from popular brands like Athleta and Lululemon reveal the presence of PFAS, toxic chemicals also found in many personal care products and non-stick pans.
Viscose is a fabric made from chemically-processed wood pulp, and sometimes bamboo fiber. Wood and bamboo has to go through a lot of chemical processing to become a soft fabric!
This raises questions like: are the chemical residues in the fabric absorbed into the skin? What environmental consequences result from disposing of the chemicals used for fabric processing?
Recommended Natural Fiber Clothing

I’ve been “detoxing” my closet for years now, phasing out my use of synthetic fabrics and trying various natural fiber clothing brands.
PACT clothing has been my go-to for close to a decade, for organic cotton basics. Their clothes all feature organic cotton, and are produced in fair-trade factories.
I get my staples at PACT: leggings, socks, tank tops, long-sleeves, sweatpants, sweaters, camisoles, and underwear.
Use my link here for 20% off your first PACT order.
Pro Tips:
- I have tried their organic cotton bras but find they are an unusual cut. I know many people love their bras, but that is the one item I’ve tried there which I don’t re-order.
- Returns and exchanges at PACT are free and easy, so you can find the right fit. Yay!
Do you favor certain types of fabric for clothing? Do you have other recommendations for natural fiber clothes?









In logic an syllogism requires that the foundation principle be true before you attempt to build conclusions from it. Signature Frequencies is not a true foundational fact. So all the speculation has to be incorrect. I am a radiesthesiologist of some 50 years and I measure that the human is not 100, but it is different for everyone at different times. And the energy rate being emitted from Egyptian cotton is 110, regular cotton 100, sheep’s wool 130, linen 100, silk 120, and nylon 1.
And the conjecture about the mixing of wool and linen is a Levitical law that only allowed the high priest to wear it–that’s all.
thank you for commenting
it did feel far fetched that linen is 5000 and all the rest r in the hundreds or less
WOW! You are the first person I’ve read who differs from the recent narrative. Thank you for sharing a different perspective.
No, mixing of wool and linen wasn’t allowed for anyone. Ex. 28:6-8 and 39:4-5 do not say wool. Some believe that is what it was saying based off the words “argaman” (purple) and “tekeleth” (sky blue). Yet, neither mean wool as some translations and extended meanings in Lexicons say they do. They are just material dyed with color’s of blue and purple. He said you were to twist those colors together with linen. Wool is not mentioned once in those verses, but in Deut. 22:11 and Lev, 19:19 it clearly says not to mix them. Maybe you are speaking of something else?
WoW, this is all so incredibly eye opening. It makes so much sense, about frequencies. A little much to grasp all together.
May I ask, what do radiesthesiologist do exactly? What an incredible thing to learn.
Please forgive my ignorance.
I am and have been very unwell, for about 30 years, no one can really tell me why. This is extremely helpful information. I was told never to wear pink, it lowers your immune system, now I understand more why.
Roberta, I looked up what a radiesthesiologist is and this is what I got…. The profession of a wandmaker, also known as a radiesthesiologist…From what I see it is used in witchcraft. Not saying that is what it is to Val, but that is what I’m seeing it say.
Val Denton, what did you use in order to do your studies and exactly what material? Wool is rarely found 100%, it is usually mixed with other material and would drop its frequency drastically. Same with 100 % cotton compared to 100 % unbleached organic cotton. She tested 100% wool and 100% cotton which I believe was unbleached and organic. So, yes, depending on the type of those materials you tested, it most certainly can change their frequency. People are the same. You will see a variation, in frequency, based on the health of the individual you tested.
Also, a little more regarding what I wrote above about the High Priests wearing a mixture of wool and linen. In Ez. 44:4-20, the priests got in trouble for defiling the things of Yah/God, having things He said not to. He then makes it very clear in Ez. 44:17…they are only to wear linen… and NO wool upon their garments. He is chastising them and telling them specifically they cannot wear wool as High Priests. Josephus even speaks about them wearing it as if it was allowed (outside the bible). However, they were not allowed to wear it and were told they would not be His priests if they continued to defile His things. Only those who follow His ordinances are allowed to be His chosen. That is one of the many reasons the Messiah had to come. They continued to defile the things of Yah, and He had to take over.
So, I’m curious – I keep finding here and in other sources that pure silk has the same (very low) frequency as polyester. Does this mean that silk, even though it is a natural fiber that’s been used for centuries (if not millenia), is also harmful for the body? No one seems to speak on this, all the attention is on linen, cotton, and wool only.
Pink is pure, unconditional love. Soft, gentle, calming & soothing. It boosts the immune system!
Hi Roberta 🙂 Sorry to hear about your troubles! That’s so long to be suffering. I am learning lots about natural and forgotten/suppressed remedies, and there was a wonder of a woman named Maria Treben. Hope it’s okay with admin if I post a free version of her book here, for the betterment of all <3 (it's online, and you can look for you ailment and see her suggestions)

Hi Val, with your measuring tool have you put linen (100) and sheep’s wool (130) together to get your own reading?
yes! I have favored certain fabrics over others….I HATED polyester since I was a kid and ALL tags (except the expensive all cotton ones) leave a red mark on the back of my neck or my left side, and ALL my clothing MUST have the tags cut off before I wear them. I much prefer the soft touch of marino wool or cashmere or cotton or the linen…just recently I have been drawn to linen and despising my microfibre sheets, not even knowing that microfibre was NOT a natural product till I started looking deeper into it.
I have to tell you, I just recently purchased some organic cotton sheets for my bed from Boll & Branch and I fell in love with them and had to buy another set, then ordered a set for my sister as well as my niece and nephew. BTW their B & B organic cotton blanket is incredible. My sleep is improved, I no longer wake up sweating….
So, I’m curious – I keep finding here and in other sources that pure silk has the same (very low) frequency as polyester. Does this mean that silk, even though it is a natural fiber that’s been used for centuries (if not millenia), is also harmful for the body? No one seems to speak on this, all the attention is on linen, cotton, and wool only.
It’s due to the processing methods used in making silk. Lots of unnatural chemicals and processing causes the silk to lose its natural frequency.
Do you know of good sources for linen bedding or clothing? Thanks!
I have ordered some linen duvet covers on Amazon as well as organic cotton sheets. Linen flat sheets don’t appear to hold up very well so I went with organic cotton flat sheets and Linen top sheets. Do a google search and you will find other good sources as well. I even found some sanitary pads made with organic cotton fill and linen outer layer from Life giving linen. Im hoping it might keep urinary tract infections at bay …I seem to be getting more of them as I get older. The pads are incredibly comfortable and its a lot simpler then I imagined it would be with reusable pads. You can even purchase the pattern for them if you are inclined to make them yourself but the price is really very affordable. Check out life giving linen: https://www.lifegivinglinen.com
I think it’s also because it is ‘animal-derived’ – they pour boiling water over the butterfly pupae to make silk, so it makes sense to me that something dead (tortured perhaps, even) would not carry a very high frequency.
Perhaps it’s due to the fact that silk worms are boiled alive and the silk extracted from them.
I want to make a healing quilt of pure linen for my daughter. If I put some pieces of 100% organic cotton in the quilt will that take away the healing factor of linen.
Thank you
Deborah
That’s a thoughtful gift for your daughter! No, cotton pieces will not disrupt the frequency of the linen.
Hi, do You know if mixed fabric of let’s say 55% linen and 45% cotton is still good to use? Is it still high frequency if it’s mixed fabric like this??
I wear mixed cotton/linen blends. It won’t be as high frequency as pure linen, but I’m comfortable with it. I don’t wear mixed linen/wool for the reason I share in the article, it cancels out the frequency.
Hi Lauren, I’d like your take on wearing polyester tops on top of wool thermals. Not sure if I should dispose of all my lower frequency clothes.
I think that the base layer (touching your skin) is what’s most important.
do u have any place that does this but for men
PACT, which I recommended in the article, has some natural fiber clothing options for men. You can also search for pure linen, cotton, or cashmere options for men at most department stores.
What is frequency of 95% organic cotton 5% elastane? Struggling to find any underwear that is 100% organic cotton.
With respect to beddings, I have just been researching alternatives to my old one (which has more than earned it’s retirement 😉 ) – and I found Kapok, which delighted me. Also supposed to have a high frequency and supposedly *actually* sustainable (as opposed to bamboo which I loved and thought sustainable, but turns out to be far from great, energetically and environmentally).
If anyone can confirm/disprove the frequency of Kapok I’d be glad to learn 🙂
With many thanks for this article! 🙂
