Sage Liquid Extract (Paraben Free)

Description

Sage Liquid Extract is extracted from the leaves of Sage plant.

Sage leaves contain 1-2.8% of essential oil. Its main components are: α- and β-thujones (35-60%), α-terpineol (0.1-9%), linalool (0.5-12%), caryophyllene oxide (1.1%), 1,8-cineole (8-23%), d-terpineol, α-pinene, myrcene, camphene, limonene, ocimene, alo-ocimene, p-camphene, aromadendrene, β-caryophyllene, α-humulene, α-maaliene, α-corocalene, β-copaene, methyl isovalerianate, camphor, viridiflor, thymol, bornyl acetate, sabinol acetate and linalool acetate.

Cosmetic Properties

Anti-microbial
Sage extracts have also shown to be effective against collagen lysis by Porphyromonas gingivalis, an organism causing periodontopathy (Alonso J, 2004).
Before tooth paste was invented, people used to rub fresh sage leaves on their teeth in order to keep them white and shining. Decoction of 20g sage leaves for 3 minutes was traditionally used as a mouth wash to prevent gum-bleeding and tooth decay.

Anti-Inflammatory
Rosmarinic acid showed anti-inflammatory activity in rat models of carrageenan-induced plantar edema. It was experimentally demonstrated that this acid acts on prostaglandins synthesis (PGE2) in a similar way to non-steroidal anti-inflammatories.
Sage extract is useful to formulate cosmetic products with anti-irritant activity. It is especially suitable to treat seborrheic dermatitis or eczema.

Anti-oxidant
Sage leaves have a well-known antioxidant activity based on their phenolic compounds content. The phenolic diterpenes showing the strongest antioxidant activity are: carnosic acid, carnosol, rosmarinic acid, caffeic acid, rosmanol and genkwanin (Deans, S.G & Simpson E.J.M, 2000).

Anti-perspirant
Externally applied thujones seem to have antihydrotic activity, since they block the nerve terminals in sweat glands and act on the thermoregulatory center of the bulb, all of which makes these compounds useful to treat bromhidrosis. An open clinical study with 80 patients suffering idiopathic bromhidrosis demonstrated the beneficial effects of sage extract (leaves infusion equivalent to 4.5g/day), during a 4 weeks-treatment, which reduced secretion by a bit less than 50%.

Astringet Activity
Sage astringent activity is due to its tannin content. Tannin-containing products act on the basis of tannins’ affinity for protein molecules. On topical applications, they coat the outermost layers of skin and mucosa, thus protecting deeper layers. They also act as vasoconstrictor agents on the small superficial blood vessels. Since they reduce fluid loss and prevent environmental damages, tannins promote tissue regeneration in superficial wounds and burns (Bruneton J, 2001).
