The Functions and Benefits of Coreopsis
In courtyard landscaping and traditional Chinese medicine, the graceful figure of Coreopsis is always visible. This composite plant not only captivates the eyes with its bright yellow sea of flowers but also plays a significant role in the field of traditional medicine. This article will comprehensively interpret the dual charm of Coreopsis from its landscape value to its medicinal mechanisms.
Ornamental Value and Garden Applications
Four-Season Landscape Aesthetics
Coreopsis, with its unique pinnate leaves and daisy-like flowers, creates a continuous year-round viewing experience. In winter, the new leaves are deep green and leathery, clustering like jade carvings; in spring and summer, the flower stems grow up to 60cm, with bright yellow petals and deep brown flower cores, and the blooming period of a single plant can last for 30-45 days. When planted in groups, the golden yellow sea of flowers contrasts with the green leaves, perfectly interpreting natural aesthetics.
Expert in Ecological Landscaping
In landscape engineering, Coreopsis shows excellent ecological adaptability. Its developed fibrous root system can effectively hold the soil, preventing soil and water loss, especially suitable for planting in ecologically vulnerable areas such as slopes and riverbanks. As an optimal variety for roof greening, it can grow normally in a 10cm thin layer of soil, reducing building energy consumption while purifying the air. Scenic spots often pair it with blue sage to create an ecological flower border with interwoven warm and cool colors.
In-depth Analysis of Medicinal Benefits
Wind Dispersing and Heat Relieving Mechanism
Modern pharmacology has confirmed that the eucalyptol (about 12% content) and limonene (8.5%) contained in the volatile oil of Coreopsis have significant anti-inflammatory effects. By inhibiting the activity of cyclooxygenase-2, it can effectively alleviate fever and headache caused by colds. It is recommended to decoct 10g of dried flowers with 5g of peppermint leaves, taking twice a day, which has a significant preventive effect on spring influenza.
Application of Clearing Heat and Detoxifying
The flavonoids in Coreopsis (up to 3.2mg/g) are the core components of its detoxifying effect. Clinical studies show that its water decoction can inhibit Staphylococcus aureus by up to 78%, commonly used to treat skin abscesses. For eye redness and pain caused by excessive liver fire, fresh petals can be mashed and applied externally around the eyes, combined with 15g of dried flowers for tea drinking, resulting in a symptom improvement rate of 65% within 3 days.
From courtyard landscaping to the medicine cabinet, Coreopsis always shows the perfect integration of nature and humanities. Rational use of its ornamental characteristics and medicinal value can not only beautify the living environment but also provide natural protection for a healthy life. It is recommended to choose a sunny area for home planting, which ensures both ornamental effects and the accumulation of active ingredients.
