Hughes continually stresses this point, explaining that to get the benefits of comfrey, it must be taken regularly and consistently. The effect of comfrey is longer lasting because it is built into the very cells of the body. It should be used, regularly, as a food, because it penetrates to every part of the body and brain, improving both the structure and function of each part.

Comfrey contains the same structural material of which the human body is built, the proteins and minerals, plus the catalysts that enable the metabolism to operate more efficiently – vitamins, enzymes, etc. Secondly, its two unique elements, vitamin B12 and allantoin act directly on the blood stream - B12 to create red corpuscles and allantoin to regulate cell formation and increase white corpuscles.

Once the blood is affected by ingesting this food, the whole body benefits, even to the tiniest hair, the most remote cell, the tips of the nails, the cells of the brain, the marrow of the bones. According to Hughes, every part of the body functions better as a result of regular consumption of comfrey, and the body as a whole, is more resistant to the attacks of disease and ageing.
