Why should you try the Weleda Arnica range? Much of our potent arnica is grown to strict biodynamic standards in Scotland’s Black Isle to ensure purity and quality, without the use of chemical pesticides or sprays. About 150 pharmaceutically active ingredients are found in arnica’s flower clusters – among these are valuable and effective substances such as flavonoids, carotenoids, sesquiterpen lactones and precious essential oils. The fine silica content helps to regenerate tissue after blunt injuries such as bruises, bumps or contusions. The highest quality of our organic Arnica gives our products their extraordinary efficacy.
