Luteolin, although the name may sound unfamiliar, is actually a natural flavonoid compound widely present in our daily diet and traditional Chinese medicine.

Simply put, it is a plant chemical weapon with multiple biological activities. From a chemical structure perspective, it belongs to the category of tetrahydroxyflavonoids and typically appears as yellow needle shaped crystals.
🌿 Core efficacy and pharmacological effects
1. Anti inflammation and anti allergy (its strengths)
Mechanism: It can inhibit the release of inflammatory mediators such as histamine and leukotrienes, while suppressing the activity of nuclear transcription factor kappa B (NF - κ B), thereby reducing the production of pro-inflammatory factors such as tumor necrosis factor alpha (TNF - α) and interleukin-6 (IL-6).
Application: This makes it potentially effective in preventing and treating inflammatory diseases such as allergic rhinitis, asthma, arthritis, and chronic enteritis.
2. Respiratory system protection
Function: It has dual effects of relieving cough and eliminating phlegm. It can inhibit the cough center, while promoting the secretion of respiratory glands, diluting sputum, and making it easier to discharge.
Application: Commonly used to treat chronic bronchitis and other respiratory diseases with excessive phlegm and cough.
3. Antitumor potential
Mechanism: Studies have shown that it can inhibit tumor cells through multiple pathways. Including blocking the tumor cell cycle, inducing tumor cell apoptosis (programmed cell death), inhibiting tumor angiogenesis, and suppressing cancer cell invasion and metastasis.
Target: It has shown inhibitory effect in research on prostate cancer, breast cancer, colon cancer, ovarian cancer, lung cancer and other cells.
4. Neuroprotection and antioxidant
Brain protection: Osmanthus extract can cross the blood-brain barrier and has a protective effect on nerve cells. It helps to reduce the deposition of A β associated with Alzheimer's disease, which may be beneficial for improving memory and preventing neurodegenerative diseases such as Parkinson's and ALS.
Antioxidant: It can eliminate free radicals in the body, increase the activity of superoxide dismutase (SOD), and protect cells from oxidative damage.
5. Cardiovascular and Metabolic Regulation
Heart protection: It has the effects of relaxing blood vessels, lowering blood pressure, and inhibiting the proliferation of vascular smooth muscle cells.
Lowering uric acid: It can promote the excretion of uric acid and has an auxiliary therapeutic effect on gout and hyperuricemia.
Anti fibrosis: It has an improving effect on liver fibrosis and pulmonary fibrosis.
🥦 Where can you 'eat' it?
Although it was initially isolated from plants in the Oleaceae family, it is widely distributed in nature. You don't need to take medicine specifically, many common vegetables and fruits are rich in luteolin (usually in the form of glycosides):
🥬 Vegetables: celery, green pepper (bell pepper), cabbage (cabbage), cauliflower, broccoli, carrots, sugar beets.
🌿 Vanilla and Seasoning: Thyme, Rosemary, Basil, Peppermint, Chamomile.
