Duoflash®: plants and essential oils combined so you can enjoy quality sleep!

Duoflash® is composed of plants and essential oils rigorously selected by Arkopharma Group experts.

  • Valerian (Valeriana officinalis). Very common in Europe, valerian helps with stressful situations or tensions caused by stress. It aids in relaxation, promoting a return to calmness in case of irritability or overwork. Another of its properties is to help preserve the quality of sleep.
  • California poppy (Eschscholtzia californica). California poppy is recognized for its beneficial effects on the quality of sleep, in particular by decreasing nocturnal awakenings. It is an excellent complement to valerian.
  • Lavender (Lavandula angustifolia). More known for its fragrance than its use in phytotherapy, lavender aids in relaxation and facilitates falling asleep, especially when combined with other plants with calming properties such as valerian or California poppy.
  • Marjoram (Origanum majorana). Indigenous to the Mediterranean Basin, marjoram is very popular in the culinary arts for its aromatic qualities. However, it offers others advantages! In phytotherapy, its essential oil, which is extracted from its flowering tops, is used to promote physical well-being and relaxation.


Designed and made in France, the Duoflash® range offers you the best of nature by combining plants and essential oils in a single gel capsule: the “CAP in CAP.” With this innovation, the active ingredients are diffused in 2 phases:

  • 1st phase: essential oils are “flash-released” for an instant boost effect  
  • 2nd phase: plants are released gradually for a longer-lasting effect
