Formulation of a mixture of free-B-ring flavonoids and flavans for use in the prevention and treatment of cognitive decline and age-related memory impairments
The present invention provides a novel method for preventing and treating memory and cognitive impairment resulting from oxidative stress, inflammation and the process of aging, as well as, neurodegenerative conditions. The method is comprised of administering a composition comprising a mixture of Free-B-Ring flavonoids and flavans synthesized and/or isolated from a single plant or multiple plants to a host in need thereof. The present also includes a novel method for simultaneously inhibiting expression of pro-inflammatory cytokines, preventing ROS generation and augmenting anti-oxidant defenses. The activity of this composition is conducive to ultimately preserving cognitive function and providing a level of neuroprotection.
1. A method for treating a subject diagnosed as having a neurodegenerative disorder, the method comprising administering to the subject a therapeutical effective amount of a composition comprising a mixture of baicalin extracted from Scutellaria and catechin or epicatechin extracted from Acacia or Uncaria.
2. The method of claim 1 , wherein baicalin extracted from Scutellaria and catechin or epicatechin extracted from Acacia or Uncaria are in a ratio of about 80:20, respectively.
3. The method of claim 1 , wherein the baicalin and the catechin or epicatechin are extracted from a plant part selected from the group consisting of stems, stem barks, trunks, trunk barks, twigs, tubers, roots, root barks, young shoots, seeds, rhizomes, flowers and leaves.
4. The method of claim 1 , wherein the catechin or epicatechin is extracted from an Acacia or Uncaria species selected from the group consisting of Acacia catechu, Acacia concinna, Acacia farnesiana, Acacia senegal, Acacia speciosa, Acacia arabica, Uncaria gambir, Uncaria tomentosa, Uncaria africana , and Uncaria gambir.
5. The method of claim 1 wherein the composition is administered in a dosage ranging from 0.001 to 200 mg/kg of body weight of the subject.
6. The method of claim 1 , wherein the composition further comprises a conventional excipient that is pharmaceutically, dermatologically and cosmetically suitable for topical application.
7. The method of claim 6 , wherein the composition further comprises an adjuvant or carrier.
8. The method of claim 1 , wherein the composition is in a controlled release form.
