According to the official instructions:
It is used for ten days in one month: 3×2 drops a day. The oil is taken after a meal, diluted in a teaspoon of edible oil (sunflower, olive, coconut, linseed…).

For children over 6 years of age:
The treatment should preferably last 10-14 days, as follows: 2-3×1 drop a day. The oil is taken after a meal, diluted in a teaspoon of edible oil. Mix the contents well and swallow quickly, without holding it in your mouth. A glass of cold water is recommended afterwards.

We strongly recommend mixing it with olive oil, mainly because olive oil largely neutralizes the pungency of oregano oil, and it also coats and protects the stomach.

The method of use in the instructions is somewhat different from what we recommend based on the experience of many users. The maximum amount of oil during the day is 12 drops. Because the oil is very strong, most infections are resolved with 9 drops of oregano oil a day. We usually advise a three-week application as follows: first week 3 x 1 drop, second week 3 x 2 drops and third week 3 x 3 drops a day.

If you follow the instructions, you can’t go wrong.
