What plants are you trying to standardize, and how do you do it?

We're working on St. John's wort (Hypericum perforatum) and echinacea (E. purpurea and E. angustifolia). Goldenseal (Hydrastis canadensis), feverfew (Tanacetum parthenium), and huang qin (Scutellaria baicalensis) are plants we're going to work on next. We may work on other plants depending on our customers' requirements.

The plants from the University of Guelph are acclimatized and grown in a controlled environment facility. It looks like a greenhouse, but it's way more than that - every aspect of the environment is controlled. We run thousands of experiments on different lines with different types of environments to make sure we get the best plants - that is, ones that are identical and have the right chemical compound contents and the same potency.

Growing in a controlled environment ensures that none of the plants is contaminated by polluted soil, which is sometimes a problem when they're grown outdoors in fields.
