First difference: the starting point
A seed is a plant structure. An extract is a material obtained by separating components from a raw material through a process. The word “hemp” does not tell us on its own which part was used or what was concentrated. “Hemp extract” therefore needs more context than an illustration of leaves.
The Catalan Food Safety Agency distinguishes products derived from seeds from questions associated with cannabinoids and other ingredients. This separation matters when understanding the food framework: not everything sharing a botanical origin belongs to the same ingredient category. ACSA: hemp and cannabinoids
Second and third: ingredient and finished product
Seed oil describes an oil’s origin. CBD identifies a molecule. A seed oil may form part of a formulation, but its name does not automatically mean the product contains a particular amount of CBD. Likewise, a preparation highlighting CBD may contain other ingredients. The complete composition needs to be read.
Imagine one label saying “hemp seed oil” and another saying “carrier oil with extract”. Even if both use an amber bottle, the descriptions are not interchangeable. This is an illustrative example, not a reference to products analysed by Milnubes. It reminds us that the container is a presentation choice, not evidence of chemical identity.
Fourth: the quantitative information
An amount in milligrams is useful only when we know which substance and which commercial unit it describes. It may refer to the total contents of a package, a concentration or an entire ingredient. “Milligrams of extract” and “milligrams of CBD” are not equivalent expressions unless information exists to relate them.
Declared contents should also be distinguished from the absence of contaminants. A correct name does not replace the relevant controls. As a documented example, AESAN issued an alert about THC in a particular batch of hemp seed oil. The alert concerned an identified product; it did not justify attributing the problem to all seed oils. AESAN: alert concerning a batch of seed oil
Fifth: the applicable framework
Spanish regulation of edible vegetable oils includes hemp seed oil and requires compliance with the applicable European contaminant limits. That reference should not be used to present every oil with added cannabinoids as authorised. The ingredient description and intended use still matter. Royal Decree 351/2025
To read a label critically, start with three lines: the product name, ingredients and quantity expressed with a unit. Then check who is responsible for the product and which documentation corresponds to its batch. There is no need to solve all the chemistry at a shop window. Simply notice when a shared image is hiding differences that should be written clearly and made easy to compare.
Take this with you
The leaf identifies a visual world. The ingredients list identifies what the package declares it contains.
