Presentation Transcript

  1. Reishi and Immunity: A Scientific Overview Presented by Michael N. Chang, Ph.D.Chief Scientific Advisor, Nu Skin Enterprises, Inc. This material has been prepared by Pharmanex to be used in conjunction with general educational events and activities only. Alterations or modifications of this presentation without the express approval of Pharmanex is prohibited.

  2. The Human Immune System 1. Removes waste and harmful material, to ensure the normal function of the body. 2. Defends against pathogens - bacteria, fungi and virus. 3. Kills and removes dead cells that have been altered as a natural process of the cell rejuvenation function. ...…is a complicated network of cells, antibodies and proteins that serves following three main functions: … is delicately balanced by a very sophisticated feedback regulation and control system

  3. Immune Cells Recognize and Destroy: Invading Organisms and Damaged Cells Chemical message alerts immune system that an invader is present Immune cell “swallows” foreign invader

  4. Cell Surface Antigen How does it work? • Pathogens, such as bacteria, fungus, virus, have carbohydrates protruding outside of its surface. • Cells that have been altered during the normal cell rejuvenation process also have carbohydrate antigens protruding.

  5. Reishi Mushroom Reishi (Ganoderma lucidum) mushroom is a fungus occurring as a shelf-like form growing on trees and stumps in densely wooded mountainous areas with high moisture and low light. The spores of Reishi have tough outer shells that make it difficult to obtain the nutrients inside. The rarity of Reishi is partly attributed to the difficulty of germination.

  7. Types of Reishi There are 62 types of Reishi, of which six are most common: RED BLACK BLUE WHITE YELLOW PURPLE RED Reishi is preferred because it can produce the highest quality extract and has been subject to the most scientific evaluation

  8. Cultivation of Reishi In 1971, Yukio Naoi, a researcher of the Kyoto University in Japan, successfully developed the artificial cultivation of Reishi, which resulted in reproducible and consistent production of Reishi.

  9. Compounds Identified in Reishi Mushrooms

  10. Reishi Spores • These highly active substances are the essence of Reishi • They are the reproductive cells that are released at maturity • However, Reishi spores are protected by an extremely hard shell which prevent us from optimally absorbing the actives

  11. Traditional Use Reishi, also known as Lingzhi, is one of the most valued herbal products in Traditional Chinese Medicine (TCM) Reishi’s earliest herbal remedies were recorded between 206 B.C. - 8 A.D. In Taiwan, families often give Reishi to their aging grandparents

  12. Clinical Research Approach for Reishi • The polysaccharides of Reishi can support our immune system. • It is generally recognized that certain polysaccharides cannot be absorbed by the human body. • When our intestine senses the presence of certain polysaccharides, receptors within our body will create a series of signals which then stimulate the body to carry out biological actions that support the immune system.

  13. Research Findings: Reishi Mushroom & Extracts • Cell support • Immune system support • Liver support • Nervous system support • Cardiovascular protection and blood sugar support

  14. Pre-Clinical Studies Animal and in vitro studies have shown that Reishi extracts: • Supports activity of lymphocytes and natural killer (NK) cells • Supports activity of cytokines and macrophages • Supports healthy, normal histamine release from mast cells Wang SY, et al. 1997;70(6):699-705. Lu Z, Lin ZB. 1994 International Symposium on Ganoderma Research, October 24-26, 1994, Beijing Medical University, Beijing , China, Program and Abstracts, p. 82.

  15. Clinical Studies In clinical studies, Reishi extracts have been shown to: • Supports healthy levels of immune cells and antibodies • Improve vigor and appetite Kupin, V. (1992). The 4th International Symposium onGanoderma lucidum, Hyatt Regency hotel, June 10, 1992, Seoul, Korea, Program and Abstracts, pp. 36-39. Yang QY, Wang, M. M. (1996). 1996 Taipei International Ganoderma Research Conference, Taipei International Convention Center (TICC), August 15-15, 1996, Abstracts, Special Lecture.

  16. Application for Reishi • Reishi supports the immune system’s ability to recognize unwanted organisms and cells that may have been damaged as a normal effect of the cell rejuvenation function. • Reishi supports optimal health • supports the body’s formation of antibodies • supports the body’s ability to proliferate immune cells • modulates the function of Natural Killer (NK) cells
