It is no secret that we do an infusion or 'digestion' of the herbs Comfrey, Calendula, and Gotu kola in to each of our face oil bases as the initial step when in production. But we wanted to share a little more about the process and why these herbs are used.
The herbs and oil are heated on a low heat which pulls the benefits of the herbs into the oil, like how a tea is brewed, but the process is done with more herbs than a tea would have and prepared at a much lower heat for a longer period.. Once the infusion is complete, the plant material is removed and the additional oils (Rosehip seed, Argan, Jojoba, Vitamin e, etc) are measured and added. The last step is to then measure and add the essential oil blend for the formula we are making. So there are herbal constituents in the face oils, but the plant material has been filtered out.
Comfrey (Symphytum officinale) – Tissue regeneration, wound-healing, and inflammation modulation actions. Responsible active constituents include Allantoin, rosmarinic acid, tannins, and triterpenoids. The Allantoin is greatly responsible for tissue restoration and wound-healing. 1
Calendula (Calendula officinalis) – Inflammation modulation, wound healing, anti-spasmodic actions. Calendula promotes healing of small abrasions, cuts, dry/cracked skin, and is anti-inflammatory. Responsible active constituents include flavonoids, saponins, and triterpenes. Calendula has traditionally been a staple for natural skin care products thanks to its healing properties. 1
Gotu Kola (Centella asiatica) – Wound healing via collagen type I Production, inflammation modulation, scar prevention, anti-microbial. Responsible active constituents include triterpenoid ester glycosides and some Beta-caryophyllene. Comfrey has traditionally been used to heal wounds as the triterpenoids are responsible for stimulating the production of collagen and some studies have shown a positive action on venous insufficiency – healing here can promote increased blood flow to the tissue allowing for proper nutrient exchange which can increase the health and healing time of the skin. 1
These three herbs have traditionally been used individually or in combination for topical applications.
