Description

A composition for enhancing immunity containing an extract of Narrow-leaf chrysanthemum as an active ingredient {A COMPOSITION FOR IMMUNE ENHANCEMENT COMPRISING NARROW-LEAF ERECTA FIG EXTRACT}

The present invention relates to a composition for enhancing immunity, comprising an extract of Narrowleaf chrysanthemum as an active ingredient, and can be used for various purposes such as pharmaceuticals and food.

All living things constantly need a lot of nutrients to sustain life, and these nutrients are always supplied from the outside in the form of food or some are synthesized in the body.

Food contains substances necessary for maintaining human life, and humans sustain life by ingesting food, digesting it in the digestive system, absorbing it, and supplying it to the tissue cells of the body.

Therefore, good nutrition maintains a healthy body, and a healthy body guarantees a healthy mind.

Nutrition is known to cause diseases directly or indirectly, and is also known to be involved in the prevention and treatment of diseases. , which can lead to various diseases.

Recently, as the standard of living increases and the diet becomes westernized, the incidence of adult diseases such as obesity, diabetes, high blood pressure, and heart disease is increasing due to overnutrition and lack of exercise.

In addition, as the population gradually ages due to the extension of life expectancy, interest in health is gradually increasing.

Health promotion aims to increase resistance to diseases, particularly chronic degenerative diseases or infectious diseases, and continuous stress, and to increase daily activity. Management that affects the overall lifestyle, such as sustainability, is required.

Immunity is a self-defense system that exists in the body, and it is a process in which the human body recognizes and removes and metabolizes various substances or living things that invade from the outside as foreign substances against itself.

It protects itself from damage caused by external stimuli or invasion of pathogenic microorganisms, but it can also damage its own tissues, such as an inflammatory response.

It modulates changes in immune function to restore normalcy or reduces the range of changes, and is classified as suppression of immune function or enhancement of immune function.

Factors that affect immune function include genetic and environmental factors, age, gender, psychological stress, nutritional status, dietary habits, and disease.

So far, health functional foods having a function of regulating immune function are divided into a function to enhance a reduced immune function, a function to regulate an excessive immune function, and a function to regulate an autoimmune function to regulate an immune response to self-components.

When the immune function is lowered, hypersensitivity reactions may occur. Such hypersensitivity reactions are diverse, such as asthma, seasonal or same-year rhinitis, allergic sinusitis, conjunctivitis, food and drug allergy, atopic dermatitis, urticaria, and allergy to bee stings. appear to be

In order to overcome immune dysfunction due to various causes, various immune enhancing agents are used, but there is a need for an immune enhancing composition suitable for long-term use and prevention because there are side effects and biosafety problems.

Leaves are alternate phyllotaxis, narrower lanceolate, and 10-20 cm long. The tip is sharp and the edge is flat or coarsely serrated.

The side veins of the Narrow-leaved Cheonenaceae are 5 to 6 pairs, and the petiole has a length of 1 to 4 cm. The narrow-leaved cheonseonseonwae has long been known in the folklore for its effects of balancing, ripening, dryness, hwasup, strong iliac crest, small bell, hwalyeol, and detoxification. In addition, it has been used in the treatment of rheumatoid arthritis, mid-stage weakness, qi and blood loss, sadisaneon, musculoskeletal separation, bruises, transpulmonary, postpartum milk deficiency, and the like.

The “immunity” refers to a mechanism to protect a living organism from disease by detecting and neutralizing pathogens and tumor cells in an organism, and the “immunostimulation” refers to various diseases such as cancer and inflammation.
