What lab testing actually tells you about a bottle of oil
9 May 2026 · 4 min read
Anyone can put oil in a bottle and write a number on the label. A certificate of analysis is what turns that number into a fact.
Potency: how much is really in there
Lab testing measures the cannabinoid content of a batch — how many milligrams of CBD and THC per millilitre. That matters because dosing only works if the strength is consistent. If one bottle is half the strength of the last, you are not adjusting your dose, you are guessing.
Purity: what should not be there
Cannabis is a bio-accumulator: it draws up what is in the soil it grows in. Testing is how heavy metals, pesticide residues and microbial contamination get caught before a bottle ever reaches a customer. This is the part of testing nobody markets and everybody should ask about.
Batch by batch, not once
A single test from years ago proves very little. Plants vary by harvest, by season and by strain, so meaningful testing happens per batch. Ask for the certificate that matches the batch you are buying — we are happy to send ours.
And what testing does not mean
A lab result is not a medical approval. Our products are complementary medicines and have not been evaluated by SAHPRA for quality, safety or intended use. Testing tells you what is in the bottle and that it is clean. It does not promise a cure, and anyone who tells you otherwise is selling rather than helping.
