forsythia suspensa extract benefits
1. Antibacterial and Antiviral Effects
Studies have shown that Forsythia suspensa extract has inhibitory effects against various bacteria (such as Staphylococcus aureus and Streptococcus) and viruses (such as influenza and herpes). Its active ingredients (forsythiaside and forsythiaside) can destroy the structure of pathogens and interfere with their replication.
2. Anti-inflammatory and Immunomodulatory Effects
Forsythia suspensa extract reduces inflammation by inhibiting the release of inflammatory factors such as TNF-α and IL-6. It also regulates immune cells, enhancing the body's defenses against infection.
3. Clear heat and detoxify
According to traditional Chinese medicine theory, Forsythia suspensa can be used to clear heat and detoxify, and is suitable for symptoms such as wind-heat and colds. It can be used in combination with honeysuckle and mint.
4. Antioxidant and cardiovascular protection
The phenolic compounds in Forsythia can eliminate free radicals and delay oxidative damage. Some studies also show that it can help improve atherosclerosis by regulating lipid metabolism.

What are the side effects of forsythia suspensa?
1. Inducing stomach discomfort: Forsythia suspensa is a common traditional Chinese medicine. It is bitter in taste and slightly cold in nature, and enters the heart and gallbladder meridians. It has the functions of clearing heat, detoxifying, reducing swelling and dispersing nodules. It is suitable for the treatment of abscesses, scrofula, wind-heat cold, high fever with polydipsia, heat dysuria and urinary retention, erysipelas and other diseases. However, since Forsythia suspensa is a bitter and cold medicine, taking it during the period may deplete one's own Yang energy. After entering the body, forsythia suspensa is usually digested and absorbed by the spleen and stomach, which may directly damage the functions of the spleen and stomach, and subsequently lead to abnormal phenomena such as abdominal pain, diarrhea and vomiting.
2. Increase the burden on the liver and kidneys: After being ingested, Forsythia is usually metabolized by the liver and kidneys and excreted from the body. If a large amount of Forsythia is taken orally, it may increase the burden on the liver and kidneys. If this continues for a long time, it may also easily induce liver and kidney diseases.
3. Inducing allergies: Some patients may be allergic to Forsythia suspensa. After taking Forsythia suspensa, such patients usually experience secondary allergic reactions such as skin itching and rashes.
