Research conducted at the University of Texas Health Science Center at Houston said that the herbal medicine from China which is used to treat patients with heart problems may have a nitric oxide levels are very high. Nitric oxide works to widen the arteries. This research was also conducted at the University Brown Foundation Institute of Molecular Medicine for the Prevention of Human Diseases （IMM） and published in the journal Free Radical Biology & Medicine.

Nitric oxide （NO） is an enzyme that plays an important role in the system of the heart and blood vessels that function as enzymes that play a role in the relaxation of blood vessels to facilitate blood flow to the heart and circulation system. In addition, the NO molecule itself also has the effect of lowering blood pressure and reduces the formation of blockages in blood vessels.

The results of research on traditional medicine of China show the primary bioactivity of nitric oxide blood vessels and the ability to change nitrate to nitrite or nitric oxide. Herbal formulas included in the traditional medicine of China, where acupuncture and massage included.

The researchers also tested this concoction through animal experiments and obtained the result that all herbs have a relaxing effect on blood vessels levels different. Human studies to date is still planned.

休斯顿德克萨斯大学健康科学中心进行的研究表明，来自中国用来治疗心脏病病人的草药可能有非常高的一氧化氮含量。一氧化氮起到扩大冠状动脉的作用。这项研究也在预防人类疾病的分子医学学院布朗基金会（IMM）进行，并且在《自由基生物学和医学》杂志上发表。

一氧化氮（NO）是在心脏和血管系统中起重要作用的一种酶，它作为酶起作用，扮演着让血管放松以便血液流入心脏和循环系统的角色。此外，NO 分子本身也具有降低血压、减少血管阻塞物生成的效果。

研究结果表明，传统的中国医药显示出一氧化氮对血管的主要生物活性以及将硝酸盐改变为亚硝酸盐或者一氧化氮的能力。草药配方包括在传统中药中，针灸和按摩也包含在其中。

研究者还通过动物实验测试了这种混合物，得到的结果是所有的草药对血管都具有程度不同放松效果。对人类的研究目前还在计划之中。
