Growing and foraging information…
Oregano is a hardy perennial that’s wonderfully easy to grow in most home gardens, thriving in sunny pots with well-drained soil. It spreads easily and can be grown in containers, raised beds, or along garden borders. While true Origanum vulgare can sometimes be found growing wild in temperate regions (especially the Mediterranean or parts of the US where its naturalized), It’s easy to confuse it with other wild mints, so proper identification is important—look for square stems opposite leaves, and that signature oregano aroma when you crush a leaf. There are several varieties, including Greek oregano (the most medicinal), Italian, and even golden or ornamental types. Select a culinary or medicinal strain for herbal use.

Safety Concerns
Drug interaction: In large amounts, it can affect someone using blood thinners and anticoagulant drugs. If you are allergic to mint, you could also be allergic to oregano.
Breastfeeding and Pregnancy: Oregano is considered safe in normal culinary amounts and even in a tea blend with a small to moderate amount. However, large medicinal amounts, especially of oil of oregano, should be used with caution, especially while pregnant, as it is a stimulant.
Other Concerns: Using oregano essential oil can be very strong and may irritate the skin or mucus membranes, so use with caution and dilute adequately.
Long-term high doses are not recommended; use with respect and moderation.
