Product Description

Ortho Molecular Products Natural D-Hist

Natural D-Hist® is a blend of flavonoids, antioxidants, proteolytic enzymes and botanicals designed to provide support for seasonal challenges caused by common environmental allergens. Natural D- Hist® includes quercetin, a powerful flavonoid, that has been used in herbal medicine to help protect blood vessels. Bromelain enhances the absorption of quercetin, while stinging nettle leaf balances the hyper-immune response. This powerful combination actively promotes healthy nasal and sinus passages for individuals with elevated histamine and respiratory irritation.

Quercetin

Quercetin is a biologically active flavonoid antioxidant that is widely distributed in plants including oak trees, onions and tea.1,2 Quercetin is described to have preliminary evidence for supporting endothelial barrier integrity and is described to influence some aspects of platelet aggregation and signalling 3

Stinging Nettles Leaf

Urtica dioica, commonly known as stinging nettles, is a plant that has been shown in herbal medicine to help relieve seasonal allergy symptoms and act as a supportive therapy to help relieve rheumatic complaints. Stinging nettle has been used as a component of prepared medicines intended for supportive treatment of rheumatic ailments. In a double- blind randomized study, 98 individuals with allergic rhinitis compared the effects of a freeze-dried stinging nettle herb powder with placebo. The study reported the extract produced positive, though limited results, in the treatment of allergic rhinitis. In a multicenter study, 152 patients with degenerative, rheumatic diseases were given Nettle Herb extract. Subjective improvement of symptoms was observed in 70% of patients.4,5 Studies have shown that the extract of stinging nettles leaf balances a variety of inflammatory activities that affect respiratory health. Stinging nettle leaf controls mastcell degranulation, prostaglandin formation, and histamine action all contributing to a balanced inflammatory response.6

Bromelain

Bromelain is a plant enzyme naturally found on the stem and fruit of the pineapple plant. Bromelain is a proteolytic enzyme that aids in in the breakdown of large protein complexes, and has been shown to enhance the absorption of quercetin.7

N-Acetyl Cysteine

N-acetyl cysteine (NAC) provides antioxidants. It is also an amino acid precursor to one of the most important antioxidants in the body, glutathione.8

Vitamin C

Vitamin C cannot be synthesized by humans and is therefore an essential nutrient that must be consumed in the diet. Among its numerous health-promoting properties, vitamin C helps in wound healing, connective tissue formation and the development and maintenance of bones, cartilage, teeth and gums and is an antioxidant for the maintenance of good health.
