What Chinese patent medicine is best for lowering high diastolic blood pressure?

There is no definitive claim about which traditional Chinese medicine (TCM) preparation is best for lowering diastolic blood pressure. Generally, TCM preparations such as Niuhuang Jiangya Wan (Bezoar Hypotensive Pills), Luobuma Jiangya Pian (Apocynum Venetum Antihypertensive Tablets), Duzhong Jiangya Pian (Eucommia Antihypertensive Tablets), Shuluo Pian (Circulation-Improving Tablets), and Xinmai Tong Pian (Cardiovascular Circulation Tablets) may be used to help lower elevated diastolic blood pressure. However, these medicines should be taken under the guidance of a qualified physician. Specific details are as follows:

1. Niuhuang Jiangya Wan: The main ingredients include antelope horn, white peony root (Bai Shao), ligusticum (Chuan Xiong), among others. This formula has effects of clearing the heart, resolving phlegm, and lowering blood pressure. It can help relieve symptoms associated with high diastolic pressure such as dizziness, vertigo, headache, and insomnia.

2. Luobuma Jiangya Pian: Main components include Apocynum venetum leaves, mother-of-pearl (Zhen Zhu Mu), hawthorn (Shan Zha), etc. It helps unblock meridians, relieve pain, calm the liver, and subdue hyperactive yang. It is effective in managing high diastolic blood pressure and can alleviate symptoms like dizziness, headache, and irritability.

3. Duzhong Jiangya Pian: Key ingredients include Eucommia bark (Du Zhong), Prunella herb (Xia Ku Cao), Uncaria (Gou Teng), etc. This formulation nourishes the kidneys and clears heat, making it suitable for patients with high diastolic pressure due to kidney deficiency and liver hyperactivity.

4. Shuluo Pian: Main components include wild chrysanthemum flower, cassia seed (Jue Ming Zi), linoleic acid, etc. It functions to clear liver fire, cool the blood, and reduce blood pressure. However, it is not recommended for patients with coronary atherosclerotic heart disease, gastric ulcers, or duodenal ulcers.

5. Xinmai Tong Pian: This contains ingredients such as angelica (Dang Gui), cassia seed (Jue Ming Zi), salvia (Dan Shen), etc. It promotes blood circulation, removes blood stasis, nourishes the heart, improves vascular function, lowers blood pressure, and reduces lipid levels. As it may irritate the gastrointestinal tract, it is recommended to take after meals.

During medication, it's important to maintain a balanced diet and consume adequate vitamins and protein—such as broccoli and eggs—while avoiding spicy and irritating foods. This supports immune function and overall health.
