Red Clover Tablets, also known as red trefoil, is distributed in Europe, the United States, New Zealand, etc. It is also cultivated south of the Huaihe River in China. The stems are erect or ascending, round with concave-convex longitudinal stripes, and 60-100 cm tall. The leaflets have light white V-shaped markings, with hairs on the leaf surface and entire margins. The inflorescences are capitate, bearing more than 100 flowers, which are reddish-purple and self-sterile. The pods are obovate with membranous pericarp, each containing 1 seed. The seeds are reniform or nearly triangular, yellowish-brown, with a thousand-seed weight of about 1.5 grams.

Red clover prefers a humid and warm climate, and is relatively drought-tolerant and cold-resistant. It grows well in well-drained, calcium-rich clayey soils. Its growth cycle is generally 2-6 years, but in warm conditions, it often shortens to biennial or annual. As a long-day crop, red clover requires more than 14 hours of sunlight to flower and set seeds. When cultivated as forage for livestock, it is usually sown in a mixture with gramineous forages; when used as green manure or feed, it is often cultivated alone. Inoculation with rhizobia can significantly increase yields. Sowing can be done in spring or autumn, with a seeding rate of about 15 kg per hectare. Drill sowing is adopted with row spacing of 20-40 cm and sowing depth of about 1.5 cm. It can be mowed 2-4 times a year. The stems and leaves are soft with a slightly bitter taste. Fresh grass contains approximately 4.1% crude protein, 1.1% crude fat, 7.7% crude fiber, 12.4% nitrogen-free extract, and 2.0% ash. The yield of fresh grass per hectare can reach 30-60 tons.

Red clover has multiple functions, including medicinal value, feed value, and greening ornamental value.

1. Medicinal Value

The entire herb of red clover can be used as medicine, with certain medicinal effects. It contains a variety of active ingredients, such as isoflavones, which have estrogen-like effects and are beneficial to women's health. Red clover also has anti-inflammatory, antibacterial, and antioxidant effects, and can be used to relieve some inflammatory diseases and enhance the body's immunity.

2. Feed Value

Red clover is a high-quality forage grass, rich in nutrients such as protein, minerals, and vitamins. It has good palatability and is favored by livestock, making it one of the important feed sources in animal husbandry. It can be used to feed livestock such as cattle, sheep, and horses, helping to improve their growth performance and production efficiency.

3. Greening and Ornamental Value

Red clover has bright and beautiful flowers with a long flowering period, thus having high ornamental value. It can be planted as ground cover in parks, courtyards, and along roadsides to beautify the environment. At the same time, red clover also has the functions of soil and water conservation and soil improvement, which plays a positive role in improving the ecological environment.

When using red clover, it should be utilized reasonably according to actual conditions and in accordance with relevant usage specifications. If it is to be used for medicinal purposes, it is recommended to do so under the guidance of a doctor to ensure safety and effectiveness. Meanwhile, when used as feed, attention should also be paid to reasonable matching to meet the nutritional needs of livestock.

Red clover (red trefoil) extract is derived from a perennial herbaceous flowering plant native to Europe, Asia, and Africa. Red clover has been used for hundreds of years for its health-benefiting properties. This red clover supplement contains an extract of the aerial parts of the red clover plant.

Red Clover Tablets, which mainly contains isoflavones, has the following efficacies:

Regulating Hormonal Balance

Red Clover Tablets has broad prospects in the health product industry. Its core active ingredients, isoflavones (such as daidzein and red cloverin), are gradually becoming important components of natural health products due to their effects such as anti-cancer, anti-inflammatory, antioxidant, and improving menopausal symptoms.

As a natural herbal extract, red clover extract has seen continuous optimization in its production processes and formulations in recent years, driven by growing consumer demand for natural health products and increasing recognition of herbal efficacy. By adopting advanced extraction technologies and bioengineering techniques, red clover extract not only enhances the concentration and bioavailability of active ingredients but also adapts to the health needs of different populations through optimized formulations. Furthermore, the introduction of strict quality control measures and clinical trial validations has improved the safety and reliability of red clover extract, boosting its market competitiveness. However, key challenges facing the current red clover extract market include further enhancing its biological safety, improving stability in complex environments, and ensuring efficacy and compatibility across diverse application scenarios.

With the development of biotechnology and health sciences, red clover extract will place greater emphasis on environmental friendliness and multifunctionality. The integration of renewable materials and eco-friendly adhesives will reduce carbon emissions during production, enhancing the product’s environmental attributes. Meanwhile, the application of gene editing and synthetic biology technologies will facilitate the development of new herbal extracts with higher biological activity and broader application ranges, minimizing environmental impact. Additionally, optimizing biocontrol strategies and incorporating multifunctional additives to improve adaptability and flexibility in complex environmental conditions represent future development directions. Nevertheless, manufacturers of red clover extract must address the challenge of controlling costs while ensuring product quality, as well as maintaining stability and efficacy across various application scenarios.
