Bog labrador provides a rare, precious and fabulous essential oil. Its effectiveness is equaled only by its very high price. In the most serious situations, it will always remain a life-saving remedy because its profile is both simple and complex, far beyond any reasoned biochemical interpretation. The therapist who has the experience knows all its value. An essential oil with great potential for the future. This plant, little used because little known and rare, offers very effective therapeutic properties.
