Broad-Spectrum CBD Oils
Broad-spectrum CBD oil and THC-free CBD oil actually name the same product: a hemp extract with the THC separated out after extraction, while the terpenes and flavonoids left in the product. At uWeed these CBD drops all come from Swiss producers and are available side by side in our shop, in concentrations ranging from 5% to 26% Cannabidiol. Every batch carries a lab report showing no detectable THC and the full assortment is available below for you to find the right product for your needs.

What is broad-spectrum CBD oil?
Broad-spectrum CBD oil is a hemp extract in a carrier oil such as hemp seed or sunflower oil, from which the tetrahydrocannabinol (THC) has been separated after extraction. The cannabidiol (CBD), the accompanying cannabinoids, the terpenes and the flavonoids stay in the extract, so the lab report for each batch shows no detectable THC content.
CBD oils, full-spectrum ones as well as broad-spectrums, are placed on the market as cosmetic or chemical products in Switzerland, never as a food and never as a supplement. Where the lines lie between the three types of extract is explained more in detail in the difference between full spectrum, broad spectrum and isolate.
What does "THC-free" mean on a CBD oil?
On a CBD oil, "THC-free" means the laboratory analysis found no THC: the value sits below the method's limit of detection, not necessarily at zero. That limit belongs to the laboratory and the method rather than to the oil — two labs measure to different depths, though generally below 0.05% and sometimes below 0.02%.
Listings write it several ways — THC-free CBD oil, CBD oil without THC, CBD oil THC free, zero THC CBD oil — and each resolves to the same line on a certificate of analysis. uWeed writes no detectable THC, because that is what the report says.
Two lines on the certificate belong together: delta-9-THC and total THC. An entry of "n.d." or "<LOD" means the method found nothing, and the threshold it would have found something above is printed in the same report. Both refer to THC and not to cannabidiol, which is worth knowing if you want to keep CBD and THC apart.
How is the THC removed from the extract?
The THC is separated out after extraction rather than avoided during it. The crude extract is produced as it would be for a full-spectrum oil; a chromatographic separation then draws off the THC fraction while the other cannabinoids and the terpenes carry on.
- CO2 extraction: the crude extract is produced from hemp biomass.
- Chromatographic separation: the extract passes through a column and the THC fraction is diverted.
- Dilution: the refined extract is brought to its target concentration in the carrier oil and bottled.
- Batch analysis: every batch goes to the contracted laboratory before sale.
Only the separation step belongs here; how the methods compare is covered by CO2 extraction of CBD.
Choosing a broad-spectrum CBD oil
A few checkable features separate one broad-spectrum CBD oil from another. Concentration determines how much cannabidiol is in the bottle, and across our range, it runs from 5% to 26%. The carrier oil decides consistency, scent, absorption and shelf life. Producer and origin decide which lab report stands behind the bottle, which for a product sold on a measurement is a checking criterion.
- Concentration: divide the bottle price by the milligrams of cannabidiol — only that figure makes a 5% oil and a 24% oil comparable.
- Carrier oil: hemp seed oil looks greenish, sunflower oil stays neutral and lighter; which carrier oil a CBD oil uses has the rest.
- Producer: THC-free CBD oil from Switzerland comes here from Naturalpes, Qualicann and Herba di Berna.
- Certificate of analysis: check that the batch number on the report matches the one on the bottle.
