Important Announcement

Dear Client,

For more than 100 years we have been producing our Haarlem Oil with the greatest respect for the traditional alchemical method. Our expertise allows us to always offer quality oil.

The manufacturing process of our Haarlem Oil always remains the same.

Our oil is unique and of irreproachable quality and is distributed at European and international level.

Recently, authorities in some European countries have recommended that the daily intake of alpha-pinene should not exceed 40 mg. Moreover, some European countries already apply this recommendation. Thus, in order to comply in these countries, our 200 mg capsule will evolve and will contain 38% Haarlem Oil and 62% linseed oil. Note that for France the original 200 mg capsule 100% Haarlem Oil is still available for a certain period.

Rest assured that this development will in no way change the quality of our products. It will even satisfy people who find the capsules a little too high in Haarlem oil and will avoid possible inconveniences for some (such as belching).

We also announce a temporary closure of our online store. (Temporary closure scheduled for mid-June)

More and more of you want to take advantage of the benefits of our Haarlem Oil. To meet this growing demand, we have set up an online store that we now need to update and develop.
