What does sulfur bring to the respiratory sphereThere are two types of bronchitis:

Acute bronchitis the most frequent and chronic bronchitis which is much more severe.

Chronic bronchitis is a disease that affects individuals working in cold or dusty environments, where the air is impure… but also and especially smokers. Tobacco smoke is identify as a specific pollutant that impairs lung tissue and leads to medium-term chronic bronchitis. The mechanism that maintains the cleanliness of the airways, is paralyzed by cigarette smoke. The particles of smoke inhaled cannot be evacuated, and the glands of the irritated airways produce more mucus. Today there are 2.5 to 3,000,000 people with chronic bronchitis.

Note that childhood respiratory infections may have a role in triggering or aggravating the disease. Chronic bronchitis is a logical complication of one or several successive attacks of acute bronchitis.



  • Acute bronchitis: very dry cough at the start and soon becoming deep and hollow. The mucus is very viscous.
  • Headaches can also be a symptom of acute bronchitis.
  • Chronic bronchitis: when cough is establish and lasts three months or more. The symptoms resemble those of acute bronchitis: a cough with sputum, wheezing and breathing difficulties, depending on the patient. If you are a smoker, be aware that the risk of developing chronic bronchitis is much higher than among non-smokers.


Haarlem Oil was discovered in 1696 in Holland by Claes Tilly, it is used in France since 1924. Haarlem oil consists of three natural ingredients: pine turpentine (80%), linseed oil (4%) and sulfur (16%) in a 200mg capsule. It has two main actions:

  • Powerful action linked to the properties of pine turpentine.
  • Clarification of many secretions including bronchial secretions, due to the sulfur.

After taking the capsules orally, the distribution of Haarlem oil in the body is rapid and widespread. The study by Professor Jacquot (1984) shows a significant and early distribution of sulfur (1 hour) at the bronchoalveolar lung tissue.

In a study conducted by Dr. B. Leroux, Haarlem oil treat 25 children with chronic pulmonary disease of various etiologies. Haarlem oil is very effective in 68% of cases after treatment of bronchitis and in 70% of cases when treatment occurs monthly.

Comment from Dr B. Leroux about his study of Haarlem Oil, administered as a treatment to 25 children with chronic pulmonary disease of various etiologies:

In 68% of cases in our series, we observed at the first course of HAARLEM OIL, clarification and disappearance of bronchial hyper-secretion in less than a week. This confirms both the positive rheological action and the antiseptic action of the HAARLEM OIL. These actions continued with a persistence of several weeks in most cases. In 70% of children for whom the renewal cycles of Haarlem Oil has been proposed monthly, the level of effectiveness continued very favorably, leading to total and permanent healing of chronic bronchitis reached in less than four months. We can measure the resulting benefits compared to multiple treatments previously used (especially repeated courses of antibiotics). In other cases, 60% of those whose monthly treatments were followed either systematically or on demand, the antiseptic action of the Haarlem oil resulted in the clarification of the trachea-bronchial secretions. The Haarlem Oil has achieved the disappearance of all symptoms of congestion during periods of varying lengths and also very significantly reduced the episodes of superinfection, only seen in children when the chronic bronchopulmonary infection is considered final.
