Cortex Phellodendri

Cortex Phellodendri

Cortex Phellodendri is originated from the dried tree bark of Phellodendron chinense Schneid. It is one of the most commonly used traditional chinese medicinal plants for psoriasis, diaper rash, infant and toddler eczema treatment.  The major active constituent of Cortex Phellodendri is berberine1.

Eczema is a common chronic itchy skin condition with high prevalence in children under the age of five, especially in the first six months. Some adolescence and adults also suffer from very mild to severe eczema. Conventional treatments include hydrocortisone cream, antifungal cream, topical or oral antibiotics, and systemic corticosteroids aimed at reducing skin inflammation.

Cortex Phellodendri has been widely used in herbal medicine for its anti-inflammatory effects.  Scientific studies revealed that the anti-inflammatory effect of cortex Phellodendri was mediated by down-regulating the mRNA expression of a panel of inflammatory mediators including cyclooxygenase-2, tumor necrosis factor-α, interleukin (IL)-1β and IL-6 1,2,3,4,5.

Other beneficial actions of cortex phellodendri include neuroprotective, anti-diarrheal and antimicrobial effects 6,7.

Cortex Phellodendri is one of the active ingredients in Unitech Medical® CamWell™ Herb to Soothe™ and Simply Baby™ botanical creams.
