I make the herbal-infused oils by placing medicinal herbs in a large glass jar. I add sunflower vegetable oil (first cold pressure) and put them under the sun of Provence and directly on the ground of the mountains for 3 weeks to 1 month. I finally filter them several times until I finish with a very fine filter. The plantain solar-infused oil can be used pure or as a basis for synergy with essential oils. The skincare products are made in Provence and in small batches with beautiful and simple ingredients. The raw materials are 100% french, natural, and organic (Nature & Progrès french certification). - COSMETIC PROPERTIES - The herbal infused oil of plantain (which I make by myself) is healing, local anti-allergic, and antispasmodic of the respiratory area. - ORGANIC INGREDIENTS - Helianthus annuus seed oil, Plantago lanceolata leaf extract. - CAPACITY - 1oz / 30ml or 3.5oz / 100ml.
