A CBD tincture is one of the simplest CBD products: a small bottle, a dropper and a measured amount of CBD in oil. Simple doesn’t mean self-explanatory, though, and plenty of advice online is out of date or flat-out wrong.
This guide covers what’s actually in an OnlyPure tincture, how to use the dropper, how to store the bottle, and how to check its lab report.
What “tincture” means here
Traditionally, a tincture is a plant extract dissolved in alcohol. Today the word is used loosely, and many “CBD tinctures,” including ours, are really CBD oils.
Our CBD Tincture contains two ingredients: full-spectrum hemp extract distillate and MCT oil, a carrier oil made from medium-chain triglycerides. There’s no alcohol base. The hemp extract is made with ethanol during processing. On the lab report for our current 1500 mg batch, ethanol is listed as not detected in the finished product.[5]
What the label tells you
Both strengths come in a 30 mL bottle with a marked dropper:
| 900 mg | 1500 mg | |
|---|---|---|
| Serving size | 1 mL (1 full dropper) | 1 mL (1 full dropper) |
| Servings per bottle | 30 | 30 |
| CBD per serving | 30 mg | 50 mg |
| Other ingredients | MCT oil | MCT oil |
The label also says the extract contains less than 0.3% THC and that “this product is not THC free.” It warns that the product is not for anyone under 18 or for anyone pregnant or lactating. It also advises consulting a physician if you have a medical condition or take medication.
How to take it
The label’s directions are to shake the bottle, fill the dropper, squirt it under your tongue and hold it there for 1 to 2 minutes before swallowing. Some people prefer adding it to a hot drink instead.
Because the dropper is marked, you can measure less than a full serving. Don’t take more than the label’s suggested amount.
What to expect, honestly. You’ll see confident claims that holding CBD under your tongue sends it straight to the brain, or that you’ll feel it in 15 minutes for 4 to 8 hours. The research doesn’t support that kind of precision.
A 2018 systematic review of CBD pharmacokinetics in humans found that peak blood levels were reached anywhere from 0 to 4 hours after dosing.[1] It also found that levels were higher when CBD was taken with food or in lipid (oil-based) formulations.[1] The authors noted how little data exists, and how inconsistent it is.[1] In short, absorption varies from person to person and with food, so pay attention to how you feel.
One important don’t: a tincture is made to be taken by mouth. Never put it in a vape or inhale it in any form.
How to store it
Follow the label: store at room temperature, and keep the bottle away from heat, light and humidity to preserve freshness. A few practical habits help:
- Keep the cap tight and the dropper clean. Don’t touch it to your mouth.
- Keep the tincture in its original amber bottle. Don’t move it to a clear or plastic container.
- Use it within the date printed on the package.
- Keep it out of reach of children and pets.
No CBD oil lasts forever. Like any product made with oils, it can change over time, especially once opened. If the smell, taste or look changes noticeably, don’t use it.
Tincture, softgel or salve?
- Tincture: adjustable amount, can be held under the tongue or added to a drink.
- CBD Softgels: a fixed amount per capsule, no taste, easy to travel with.
- CBD Salve: made for use on the skin, with mango butter, shea butter and essential oils.
Our tincture is made to be taken by mouth. If you want something for your skin, use a product formulated for skin, like the salve, rather than oral oil.
How to check what’s in your bottle
Every batch of our tincture is tested by an outside lab, and the certificate of analysis (COA) is linked on the product page and on our Product COAs page.
The current reports come from the Utah Department of Agriculture and Food lab:
- 1500 mg: lot 251210-2, issued May 15, 2026. It reports Δ9-THC at 0.18% by weight, and PASS results for pesticides, heavy metals, residual solvents, microbials and mycotoxins.[5]
- 900 mg: lot 250721-1, issued February 9, 2026. It reports Δ9-THC at 0.10% by weight, and PASS results across the same panels.[4]
A few things worth knowing when you read these:
- A COA describes the specific sample tested. Compare the lot number with your package.
- “ND” means not detected, “<LOQ” means below the level the lab can measure precisely, and “PASS” means under the lab’s limit.
- Lab testing shows what’s in a product. It isn’t FDA approval, and it doesn’t prove the product will do anything for a health condition.
Before you start
- Medications: the FDA warns that CBD can cause liver injury and can interact with other medicines.[2] Combining CBD with alcohol or other drugs that slow brain activity raises the risk of sedation and drowsiness.[2] Talk with your doctor first.
- Pregnancy and nursing: the FDA strongly advises against using CBD during pregnancy or while breastfeeding.[3]
- Drug tests: our tincture is full-spectrum and contains a small amount of THC. In one small study, half of the adults who used a full-spectrum, high-CBD product daily for four weeks tested positive for a THC metabolite.[6] If you’re drug tested, keep that in mind.
