@fify-- Yea, oregano oil is very strong. What I do is I put a drop of it under my tongue so that I don't taste it as much and drink something quickly afterward.
There are also oregano capsules but I've never taken them so I don't know if they work.
When there is a recurring and systemic candida infection, it's very hard to get rid of it. Some people think that they can take oregano once or twice and it will go away. But it needs to be taken regularly to show its effect completely. Oregano inhibits candida yeast from multiplying, but if you have a huge infestation, that means you have to take the oregano every day for months to reduce candida numbers.
