Ask Plant Therapy’s Experts: CBD!

Welcome to our series for Plant Therapy blog: Ask our Plant Therapy Experts! Where you ask, and we answer your most burning oily questions.

Wondering who your official Plant Therapy Aromatherapists are? You can get the full introduction to our whole team on our Meet Our Aromatherapists page! Because Plant Therapy is dedicated to being transparent with our customers, we knew we wanted to introduce you to the team behind answering your essential oil questions.

This June, Plant Therapy released our first-ever CBD products! We were very excited and proud to be launching such a ground-breaking product. Our company stance is that we offer essential oils because we want to do the most good we can, for the most people. This drives our pricing, company values and so much more. CBD has huge potential to benefit many people, and do a lot of good.

But CBD as a topic is fraught with misinformation, legal grey areas and confusing concepts, which is why we’re here to help! This month, for our August edition of Ask Our Experts, we’re tackling CBD.

Can you use Plant Therapy’s CBD topically?

Megan Lass asked:

I know it’s designed for internal use, but can Plant Therapy CBD oil be used topically as well?


We get this question a lot – and it’s no wonder why. CBD applied topically for pain is incredibly common, and many people suffer from chronic localized pain and hope CBD will help. We hear you!

But the answer to this question is a little more complicated and has to do with how much CBD your body can absorb when used in different ways. Let’s talk about why in more depth:

To talk about CBD and if you can (or should) use it topically, we have to talk about something called bioavailability.

CBD products come in many forms, including salves, lotions, tinctures, oils, liquids, capsules and more, and on top of that CBD also come in different concentrations. But each of these methods also requires different usage methods.

Bioavailability, or the rate at which a substance is absorbed into the bloodstream, is the other factor in the ‘which CBD serving size/product is right for me’ equation. In addition to the strength of your CBD product, bioavailability will determine how much of the CBD actually makes it into your bloodstream. Fun fact: Bioavailability isn’t just for CBD! Your doctor uses this known factor to calculate any standard dose of any drug you get via prescription.

Bioavailability is not just about the serving size of your CBD, but is also affected by the method of consumption or use.

When used topically, your skin takes a while to absorb the products and is not the most direct way to reach your bloodstream. When applied topically, only about 5% of the CBD you use will actually make it into your bloodstream. That means if you take a 100 mg serving size and use it topically, only 5 mg actually makes it into your bloodstream, and generally, it takes about 15 mg to even start to see a difference in symptoms.

Now that doesn’t mean that using CBD topically won’t work for you! Many people report topical CBD is very beneficial, but this may vary from person to person, and it’s a little harder to measure.

But when taken sublingually (as Plant Therapy CBD is designed to be taken), your absorption rate shoots up to 12%-35%, which is actually pretty high!

Sublingual use involves dropping the CBD liquid into your mouth and holding it under your tongue for 60 seconds. This method increase is due to the sublingual gland under your tongue. When a substance is administered to this gland, it gets absorbed directly into your bloodstream. That means that for every 100 mg serving size of CBD taken sublingually you absorb 12-35 mg, more than enough to potentially see effects. And as a bonus, it works much faster as well! Because this method of use is more direct, it impacts your body much sooner than even taking CBD orally, and simply swallowing it.

So while the short answer is that it won’t hurt you to use Plant Therapy’s CBD topically (it is a natural product after all!) it isn’t the most effective use of your product. Here at Plant Therapy, we wanted to make sure that our first CBD product was the most effective product to pass on to our customers!

Choosing a CBD that works for you

Rebeka Pickett says:

I still feel overwhelmed by really what to choose.

Rebeka, we know that choosing a CBD serving size that works for you can be confusing! But honestly, like essential oils, choosing the correct CBD product is all about paying attention to your own body.

If you’re ready to try CBD but aren’t quite sure which strength is right for you, choosing can seem complicated.

Just remember this: Each bottle of our Hemp Extract (CBD) was formulated with different needs and levels of use in mind.

100 mg/6 mg serving size bottle of CBD

If you’re just starting to explore CBD as a natural way to support your endocannabinoid system for better overall health, our 6 mg serving size of CBD is the perfect place to start. With a serving size just high enough to test out the flavor and explore possibilities, 6 mg is ideal to figure out how CBD can work for you and if you like the flavor you chose.

This serving is just enough to tell you if you’ll like the flavor and effects of ingesting our CBD and lets you move up to a stronger serving if needed.

500 mg/16 mg serving size bottle of CBD

If you’re looking to support your endocannabinoid system and overall health in a natural way, and you’re looking for a good entry-level CBD product for everyday use, our 16 mg per serving of CBD was made with you in mind. A 16 mg serving allows you to find the unique amount for daily use ideal for your body.

The 500 mg strength is designed for people who have minor issues that supporting your endocannabinoid system functioning may help, like mild anxiety, minor sleep problems and more.

1000 mg/33 mg serving size bottle of CBD

If you’re ready to support the overall health and function of your endocannabinoid system on a daily basis in a natural way, our 33 mg serving of CBD was designed for your needs. With an amount formulated for regular, everyday use, 33 mg is perfect for use as a supplement to maintain long-term healthy function.

This serving strength is the best option for people who are looking to use CBD every day in support of their endocannabinoid system for issues such as insomnia, more acute anxiety and minor perceptions of pain.

2500 mg/83 mg serving size bottle of CBD

If you’re a CBD user, have a medium to large body mass, high metabolism, or have more serious concerns associated with the endocannabinoid system, our 83 mg serving of CBD was designed to work for you. Formulated for robust everyday use, 83 mg was created as a supplement to maintain long-term healthy functioning in people with more severe symptoms.

This serving strength is best for those who have more severe or acute issues, but again, please remember to consult with your doctor if you are already taking medications.

Choosing a serving size:

Choosing a serving size is slightly different than choosing a strength. Your serving size refers to how many dropperfuls you choose to take per serving.

Everyone responds differently to CBD, so it’s important to pay attention to your own body’s needs. Determining the ideal serving for you may take some trial and error. With this in mind, we recommend starting with a low serving, gradually increasing as needed. You may not need to continue increasing your intake once you find a serving that works best for your unique body.

Here is Plant Therapy’s serving size chart that goes into more detail. You can also download your own copy of our serving size chart to keep on hand.

So basically, CBD may be the right choice for your body, but remember to use our serving guidelines and make sure to consult with your doctor if you are already taking medications or looking for relief from serious chronic issues.

Will I pass a drug test, and is CBD safe for children?

Monica wants to know:
I’m in the Air Force and get drug tested randomly, I know CBD isn’t the same as THC, but just wondering if I would test positive if I use CBD OIL!? Also, is it safe for kids?
Hi Monica! First, thank you for your Air Force service!
For your first question: There haven’t been enough studies done on humans yet to fully commit to saying CBD is safe for children or not, and research is what we at Plant Therapy base our products’ safe usage instructions on. So at this time, we have to say that our CBD products are not designed for use with children. I know that might be disappointing to hear, but we take the safety of our products very seriously when it comes to our little ones.
Secondly, we do have an answer for you regarding drug testing, but keep in mind we are not experts in how the US Military handles drug testing, so be sure to do your own research!

CBD is a non-psychoactive cannabinoid. Cannabinoids themselves (like CBD) can’t cause the “high” feeling associated with marijuana use. That comes from Delta-9 Tetrahydrocannabinol (or THC), a different chemical compound found in cannabis and the culprit behind that high feeling.

There are two common terms you’ll see when describing CBD products:

  • Full-spectrum CBD: Contains trace amounts of THC. The legal limit for these types of products is less than 0.3%.
  • Broad-spectrum CBD: Starts as full-spectrum CBD, and when the THC is removed, it becomes broad-spectrum.

Both broad-spectrum and full-spectrum CBD contains all the other beneficial chemical constituents of the hemp plant, which means you get all the benefits of the other chemical constituents (called the “entourage effect”), as well as the benefits of cannabidiol (CBD), and the useful terpenes, all without the “high” feeling.

Plant Therapy’s CBD is THC-free, meaning it contains no (0.0%) THC. You can investigate for yourself even further by checking the actual test results, available on each product page.

So the short answer is: CBD should not show up on a drug test. 

But despite there being no THC in our CBD, there’s another thing to consider: The kind of test being performed.

There are two types of drug tests. One looks for cannabinoids and this test is no longer legal due to CBD now being federally legal. That said, some companies may not have updated their testing requirements to meet this new legal standard.

Most workplace drug screens and tests now target delta9-tetrahydrocannabinol (THC) and do not target or detect the presence of cannabidiol (CBD) or other legal natural hemp based constituents.

I would assume that the Air Force is probably up-to-date on the legalities surrounding testing for THC, but I would always recommend checking with your superiors to learn which type of drug test they perform, and their stance on the use of products like these.

Shipping outside the USA…

Katie says:
When will this be available outside of the US?
Katie, we have sad news for you. Because of the legalities of CBD, and the fact that those laws change drastically from country to country, at this point we can’t offer international shipping on our CBD product. We wish we could, as we know we have many customers not living here in the United States (which still has some places where CBD cannot be shipped), but we want to protect not just ourselves from potential legal consequences, but you as well.
Just rest assured that as soon as we can ship internationally, we will shout it from the rooftops!

  • how are the ingredients from the plant removed and added to the oil? I am interested in full or broad spectrum but it is my understanding processing methods involving heat alter the structure of some of CBD precursor molecules that are necessary to get the desired benefits that one would want from a non isolate oil, some of the studies I have read suggest that as we are gaining a greater understanding of each of the different possible isolates, that CBD works is more useful when combined with some of its precursors as you have eluded too, additionally studies done on other isolates like the original molecule CBD starts from (similar to a stem cell before it differentiates into a specific cell and still has the ability to become any type of cell initially) the stem cell of CBD or very early stage molecular CBD precursor has been found to be exponentially more effective or potent in the body doing the same things CBD does but is like turboCBD, but again like stem cells its much more difficult to isolate this precursor that is so easily transformed into many different isolates depending on the specific hemp plant are all possible indgredients like CBD and there are so many and its so complex we are just now starting to break down and still discover all of these potential molecules, but again as you touched on depending what effects you want the isolates are more effective when combined together, but in short I think I recall heat is one factor that alone will cause a handful of molecules to change to CBD or to a molecule that will not be absorbed by the body at all or as you explained bioavailability in one post basic some compounds would be transformed to one with zerobioavailability no matter what form they were introduced to the human body, it has been a while since I took the some CE’s that talked about the specific different isolates and there were so many forms of “CB_” ie like CBA, CBG, CBE idk I don’t have them memorized anymore and without writing a book or copying and pasting and citing my own sources I don’t know if I’m making any sense, but basically I want to know if you can explain what your company does although it is not the least expensive route but it is the accepted method to remove all of these precursors that each work like CBD but are like the care bears and they all have to work together to get the best benefits but are easily converted into other substances if the chemists aren’t using the specific methods that dont break down the “active ingredient” and I know its all very complex to explain while on the same level is common sense when you think in terms of how heat pretty much alters everything in the world if us use enough of it right, and since these are not cheap to buy, but also not cheap to make if done correctly and then there’s the grey are where companies bc they aren’t evaluated by the fda are able to mislead consumers with out technically providing false information. One of the reasons I use Plant therapy is because it seems to be the most transparent and upfront with consumers since CBD has become popular many cosmetic companies that are considered reputable brands advertise they contain CBD but in reality the CBD is not in a fomr useful to humans and rarely do I find brands that use third party or independent companies to analyze there products and agree that whats advertised a beneficial ingredients included are measured at the same level as the third party companies, anyway, if someone could just touch on the methods plant therapy uses to preserve some of those important precursor and explain what methods are used by others that are not advised or effective/efficient but misleading and not equal. if its too complicated to address I understand because I don’t know how to simplify it myself it without being overly technical but still be accurate , I’d really like a full spectrum oil that truly is one and I believe if a thre were to be a broad or full spectrum CBD oil that was actually legit I think plant therapy may be the ones to offer it and charge the fairest price possible because they know if there product works it doesn’t need to be excessively over priced to be popular and still make a profit for the company, consumers just want to be getting what they think there paying for if that holds true they cannot fail, thanks for your time and insight!

    1. Hello! Great question. CBD extracts are obtained through a pressurized solvent extraction method. The solvent ethanol is used due to the affinity to cannabinoid acid to decarboxylation in the presence of ethanol at low-to-no-heat that allows for the conservation/preservation of the molecular structures, followed by chromatography recycling to increase yield and purity. As for adding it to the MTC oil: once we get the CBD it comes hardened and we have to slowly melt it down and the rest we are not allowed to go into that as it is proprietary. Thank you for your question and have a great day!

  • I would just like to say that even though I am still kind of confused about what strength to take/ how much/ why, it’s not for a lack of information. I am so grateful that PT has taken on the real work of RESEARCHING and EDUCATING instead of just selling a product and making a bunch of claims. I’m not quite sure which of these is right for me, and what it will help me with specifically, but once I figure it out I will surely be buying PT CBD. In the meantime, I will keep reading all the literature and resources PT posts. Thanks again for being such an awesome company. I really feel like you prioritize education when so many other companies do not, and I appreciate it.

  • I love how committed PT is to transparency and educating their consumers! This article was very informative and answered a lot of the questions I had surrounding CBD! Thank you!

  • I really appreciate how informational and educational this blog post is. I learn so much more from Plant Therapy. I will definitely budget in a cbd product and leave my feedback review. Relieved that cbd won’t show up on tests.

  • Should CBD be stored in the fridge once it’s been opened? How long is that shelf life after opening it?

    1. CBD should be stored in a cool, dark place and the shelf life is about 1-2 years depending on how it’s stored.

  • Ahhh I didn’t take into the account of broad and full spectrum cbd oil. Now I know why I’m taking more of the 1000mg Plant Therapy than I was with the other cbd oil company. They were full spectrum and Plant Therapy is all broad spectrum. So my best bet would be to get Plant Therapy’s 2500mg Broad Spectrum? Take less? I’m looking for pain relief, don’t get me wrong, the Plant Therapy 1000mg broad spectrum works…for anxiety, just not for pain management. I have horrible anxiety while driving and I used 1ml of 1000mg PT CBD oil and let sit sublingually for more than 60 seconds and waited about 5-10 minutes before I started driving, no panic attacks! Very pleasant flavor too, so surprising! All the other cbd oils I have tried were absolutely horrendous! Just god awful tasting, but Plant Therapys cbd oil is surprisingly good! Love the pineapple flavor!

  • I think this needs allot more studying, everyone is getting in this ban wagon and it’s really being marketed in 100 fold. I just think it needs allot more testing. I did buy some capsules not from you that was supposed to have 15% of THC and get rid of back pain……. it did nothing, I could not even tell I took anything. When I do try it again it will be from Plant Thearpy. If it doesn’t work I’ll be able to return it , and get my money back so I can’t loose with Plant Thearpy!! Thank You!

    1. Pretty sure 15% THC is illegal, CBD can only contain 0.5% or less THC to be “legal”. THC is what makes you “high” it does not help with pain. If you were told that, you were scammed by an unscrupulous seller who took advantage of your lack of knowledge. You can research all this information online – it will help you in your search.

  • Great information! I have been hearing about CBD oil and curious about it. I suffer from both chronic pain and anxiety, this seems like it might possibly help me with both issues! I’ve never used CBD oil in the past, so wondering if I should start with a really weak strength or go for a stronger one to see if it actually helps my symptoms (primarily my chronic pain issues).

  • Thank you for posting this. I have become more curious about CBD and this is an excelletn resource. You’ve answered many of my questions!

  • Wow that was a lot of information to absorb!! One of my big questions was about drug testing. Now I know I will need to ask my employer what kind of testing they do before I consider buying CBD oils.
