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.

    休斯頓德克薩斯大學健康科學中心進行的研究表明，來自中國用來治療心臟病病人的草藥可能有非常高的一氧化氮含量。一氧化氮起到擴大冠狀動脈的作用。這項研究也在預防人類疾病的分子醫學學院布朗基金會（IMM）進行，并且在《自由基生物學和醫學》雜志上發表。

    一氧化氮（NO）是在心臟和血管系統中起重要作用的一種酶，它作為酶起作用，扮演著讓血管放松以便血液流入心臟和循環系統的角色。此外，NO 分子本身也具有降低血壓、減少血管阻塞物生成的效果。

    研究結果表明，傳統的中國醫藥顯示出一氧化氮對血管的主要生物活性以及將硝酸鹽改變為亞硝酸鹽或者一氧化氮的能力。草藥配方包括在傳統中藥中，針灸和按摩也包含在其中。

    研究者還通過動物實驗測試了這種混合物，得到的結果是所有的草藥對血管都具有程度不同放松效果。對人類的研究目前還在計劃之中。
