While "food herbs" such as garlic and oregano oil are relatively safe and can be bumped up in terms of dosage, Wormwood is widely recognized as a mild poison which shouldn't be taken for more than a couple weeks. Long term use can damage the central nervous system, and many countries have banned the sale of Wormwood . Accordingly, I wouldn't suggest increasing the recommended Wormwood dose. I would think the other two ingredients to be less problematic.
