The route. Oil is oral: it is swallowed, it meets hepatic first-pass metabolism through CYP2C19 and CYP3A4 and then UGT1A7, UGT1A9 and UGT2B7, and it produces measurable plasma CBD within hours. A topical acts where you put it, and the human data on how much gets anywhere else is thin. In the largest controlled study, 46 healthy adults used a CBD cream, lotion, patch, balm or gel twice daily for 9 days. Transdermal absorption was observed for three of the five active products, concentrations peaked after 7 to 10 days, and the highest came from the lotion, which held the most CBD and a vitamin E permeation enhancer.
A 2021 position paper reviewing dermal CBD reached the blunter version of the same point: no good quality human in vivo data existed, dermal absorption was likely under 10 percent of oral, and there was not enough information to carry out a risk assessment. Meanwhile the oral side has a lever nobody can offer for a topical. A high-fat, high-calorie meal raised peak CBD concentration 5-fold and total exposure 4-fold at 750 and 1,500 mg doses.
It shows up in what you can reasonably expect. A cream is an oil-in-water emulsion; Endoca’s Salve with 250mg-750mg CBD and Whipped Body Butter are built from botanical oils and waxes with no water phase, which is why they are labeled salve and butter. That changes feel and spread, not pharmacology. What it does not change is the dose problem: nobody can tell you how many milligrams a smear delivers, because amount, area and skin all vary and none of it has been measured in a human.
The clinical picture is mixed and small. A 4-week randomized trial in 29 people with symptomatic peripheral neuropathy used a topical CBD oil at 250 mg per 3 fluid ounces and reported statistically significant reductions in intense pain, sharp pain, and cold and itchy sensations. A crossover trial in 15 adults found topical CBD gel did not speed muscle function recovery or reduce soreness after muscle-damaging exercise. A 2026 systematic review of three trials in chemotherapy-induced peripheral neuropathy, including one topical CBD arm, found no improvement over placebo. One small positive, two negatives.
Only one of these two formats has a measured systemic profile, and they answer different questions anyway. On the topical side, systemic absorption is small, slow and absent for some products entirely, the local dose is unmeasurable, and the trial record is one small positive against two negatives. Anyone promising a topical effect size is ahead of the evidence.
These are not substitutes, so the choice is about what you are trying to do rather than which is stronger. Use the oil when you want a measurable amount in your system on a schedule you control, 5 mg at a time. Use a salve or the body butter when you want something on a specific patch of skin, and judge it on how the skin feels rather than on an absorption claim. If someone sells you a topical on the basis of bloodstream levels, the evidence does not support them. Patch test a new topical on a small area first.
Hemp-derived CBD at or below 0.3 percent delta-9 THC left controlled substance status under the 2018 Farm Bill, and from 11 December 2026 Public Law 119-37 applies a total THC test with a 0.4 mg per container cap on finished products, excluding cannabinoids synthesized outside the plant. From there the formats diverge. An ingestible is a food and supplement question, and FDA has not concluded CBD can lawfully be sold in a dietary supplement. A topical sold to moisturize or soften skin is a cosmetic, while a topical sold to treat pain is an unapproved new drug, which is why this page reports trial results rather than making product claims.
Topical CBD was well tolerated across the 46-person study, with no detectable blood THC, though nine participants showed oral fluid THC at or above 2 ng/mL. The 2021 dermal review was more cautious: there was not enough pharmacokinetic or toxicity information to perform a risk assessment, and repeated application could accumulate in skin layers and diffuse slowly afterwards. For the oil, the relevant points are interaction through CYP2C19 and CYP3A4 and the gastrointestinal adverse events seen at high trial doses.
The extract going into the drops and into the salve comes from hemp grown on our own land and processed with our own supercritical CO2 equipment, with batch reports published since 2010 at lab.endoca.com. HPLC sets the cannabinoid numbers, NMR confirms them, and the pesticide, heavy metal and mycotoxin screen covers more than 200 compounds. For a topical the limit of that certificate is sharper than usual: it states what is in the jar, and no laboratory method tells you what crosses skin.
Sometimes, in small amounts, slowly. In 46 adults using five commercial CBD topicals twice daily, blood CBD was measurable for three of the five products and peaked only after 7 to 10 days of use. For the remaining two it was not detected at all.
The trial record is thin for both and mixed for topicals. A 4-week trial in 29 people with peripheral neuropathy reported lower pain scores with topical CBD, while a muscle recovery crossover and a 2026 review of chemotherapy-induced neuropathy trials found no benefit over placebo.
Not as such. The topical range is the Salve with 250mg-750mg CBD, the Whipped Body Butter at 450mg-1500mg CBD and the Mint Muscle Salve. Those are oil and wax formulations rather than water-based creams, which changes how they feel and spread.
No published human study answers that. The amount applied, the area covered and the condition of the skin all vary, and the 2021 dermal review found no good quality human in vivo data. The milligram figure on the jar describes the jar’s contents.
