Appearance

A short-lived perennial herb with a growing season of 2-5 (-9) years.

Roots

The taproot penetrates up to 1 meter deep into the soil. The stem is stout, with longitudinal ridges, erect or procumbent, and sparsely pubescent or completely pubescent.

Leaves

The leaves are palmately trifoliate; the stipules are subovate, membranous, with 8-9 veins on each side, amplexicaul at the base, and acuminate at the free part with a spiny tip. The petioles are long, with those on the upper stem being shorter, and covered with extended hairs or completely pubescent. The leaflets are ovate-elliptic to obovate, 1.5-3.5 (-5) cm long and 1-2 cm wide, with an obtuse, sometimes slightly concave, apex, and a broadly cuneate base. Both surfaces are sparsely brown and pubescent, often with V-shaped white spots on the leaf surface. The lateral veins are about 15 pairs, splaying at a 20° angle and bifurcating at the leaf margin, extending to form indistinct, blunt teeth. The petiolules are short, about 1.5 mm long.

Flowers

The inflorescence is globose or ovate, terminal; pedunculate or with a very short pedunculate, enclosed in the stipules of the terminal leaves, which expand into a flame-shaped bract, with 30-70 flowers clustered together. Flowers are 12-14 (-18) mm long and almost pedunculate. The calyx is bell-shaped, long-pubescent, with 10 veins. The calyx teeth are filiform, awl-apexed, and longer than the calyx tube, with the lowest tooth twice as long as the others. The calyx throat is open, with a thickened, hairy ring. The corolla is purplish red to pale red. The standard petal is spoon-shaped, with a rounded, slightly concave apex and a narrow cuneate base, distinctly longer than the lateral and keel petals, with the keel slightly shorter than the lateral petals. The ovary is elliptical, the style is filiform and elongated, and the ovules are 1-2.

Fruit

The pod is ovate; usually with one oblate seed.

How does the red clover good for blood pressure?

Red clover (Trifolium pratense, synonym red clover) is believed to have a good effect on blood pressure regulation due to the fact that it is rich in active constituents such as isoflavones. The following provides an overview of its potential influences and related scientific evidence:

1. Isoflavones Vascular Modulatory Effects

Red clover contains isoflavone constituents such as daidzein, genistein, and biochanin A. Isoflavones have phytoestrogenic activity and it may affect blood pressure through the following mechanisms:

Vasodilation: Isoflavones induce endothelial release of NO, which relaxes vascular smooth muscle and increases blood flow resistance, banance the blood flow.

Anti-inflammatory and Antioxidant Effects: They suppress vascular inflammation and oxidative stress, maintain endothelial function, and indirectly stabilize blood pressure. keep the blood pressure under the peace level.

2. Clinical Research Evidence

There are a few studies that confirm the blood pressure-lowering effect: A new small 2015 human study (Journal of Clinical Hypertension) indicated that red clover extract produces a moderate blood pressure-lowering effect in people with mild high blood pressure, although it is weaker than that of typical antihypertensive drugs. Controversies and Limitations: Existing studies have small numbers of participants and conflicting results. The National Institutes of Health (NIH) was not convinced by the evidence to recommend this supplement as a second-line treatment for blood pressure.The more research need to be confirm.

3. Other Synergistic Benefits

Improve Lipid Metabolism: It can indirectly contribute to cardiovascular health by lowering low-density lipoprotein (LDL) cholesterol and inhibiting arteriosclerosis.It can help people to improve the metabolism function.

Symptom Relief of Menopause: Can level swings in blood pressure or flashes of heat that occur as a secondary effect of hormonal imbalance in women during menopause. It is helpful for menopausal women.

4. Recommendations and Precautions

Dosage and Form: The typical supplements are in capsule or tea form. The dosage of isoflavones should not be more than 40-80 mg (under a doctor's supervision).

Contraindications: Use with caution in pregnancy, hormone-sensitive disease, and anticoagulant therapy, as it influences drug metabolism.

Blood Pressure Monitoring: Blood pressure monitoring is necessary if supplementation is to be attempted to avoid hypotension caused by concomitant use with antihypertensive agents.

Summary: Clover is mildly able to regulate blood pressure via phytoestrogens and antioxidant effect, but evidence is weak that this happens and it is not to be utilized in place of drug therapy. Dietary supplements (such as herbal teas) are recommended to be added to lifestyle modifications such as reduced salt intake and regular exercise. If there is necessity for systematic hypertension control, a doctor should be seen to devise an individualized plan.
