传言生姜真的能治疗哮喘病吗

The Ache: Some 26 million Americans suffer from asthma -- a chronic inflammation of airways in the lungs that causes coughing, chest tightness, wheezing and shortness of breath, according to the American College of Allergy, Asthma and Immunology.
病痛：美国过敏、哮喘与免疫学院(American College of Allergy, Asthma and Immunology)发布的数据显示，大约有2,600万美国人患有哮喘。这是肺部呼吸道的一种慢性炎症，能引发咳嗽、胸部压迫感、气喘、以及呼吸急促等病症。

Since you can still have an asthma attack despite regular medications, many patients try alternative treatments -- but there is little evidence they work, clinicians say.
即便接受常规治疗，哮喘仍然会发作，因此许多患者都在尝试另类疗法。但临床医生指出，目前还几乎没有证据表明这些疗法有效。

The Claim: Ginger, a root known for its strong, earthy flavor, can help ease symptoms of asthma by opening constricted airways.
主张：生姜这种有强烈、质 气味的植物根茎能够使原本收缩的呼吸道通畅，从而有助缓解哮喘症状。

The Verdict: Ginger, well known as a therapy for an upset stomach, is recently getting attention among scientists for what appears to be its capacity to open constricted airways -- demonstrated in several recent studies, in animals and in human cells tested in a lab.
定论：生姜用于治疗胃部不适的功效广为人知，最近它又引起了科学家的关注，因为近期针对动物和人体细胞的几项实验室研究显示，生姜似乎能够使收缩的呼吸道更加通畅。

Human tests, however, are needed to show efficacy, says American College of Allergy, Asthma and Immunology President Michael Foggs. If ginger does prove useful, he adds, it most likely would be taken with existing medicines that control the underlying airway inflammation.
但美国过敏、哮喘与免疫学院院长Michael Foggs表示，上述功效仍需要通过人体实验的验证。他补充说，如果生姜被证实的确有效，就很可能被用来与控制潜在呼吸道炎症的现有药物同时使用。

Ginger can be ingested as a fresh root or in capsules as a dietary supplement. In traditional Chinese medicine, it would typically be consumed as a tea -- generally with up to a dozen other herbs -- as a treatment for certain types of asthma-like symptoms, says Allen Sayigh, manager of the Chinese herb dispensary at Bastyr University in Seattle.
生姜既可以新鲜根茎的形式摄入，也能以作为食物补充剂的胶囊形式摄入。西雅图美国巴斯帝尔大学(Bastyr University)中药部经理Allen Sayigh说，在传统的中药中，生姜通常是作为一种茶饮──往往与十余种其他草药同时使用──用于治疗某些类似哮喘的症状。

Recent research has found ginger works by simultaneously inhibiting an enzyme that helps cause airway muscles to constrict and activating another enzyme that tends to relax the airways, says biomedical engineer Elizabeth Townsend, co-author of a study published online in the January issue of the American Journal of Respiratory Cell and Molecular Biology.
生物医学工程师汤森(Elizabeth Townsend)说，最近的研究发现，生姜可以抑制一种导致呼吸道肌肉收缩的?，同时激活另一种会使呼吸道放松的?，从而发挥疗效。汤森合着的一项研究被刊登在《美国呼吸道细胞和分子生物学期刊》(American Journal of Respiratory Cell and Molecular Biology) 1月份网络刊上。

The study, which tested the effects of ginger components on isolated human airway cells, found ginger worked particularly well in combination with a medication currently used in bronchodilators asthmatics carry in case they have trouble breathing.
这项研究测试了生姜成分对单独的人体呼吸道细胞的影响，发现当生姜与另外一种现有药物同时使用时效果尤其显著。上述现有药物被用于哮喘患者呼吸困难时使用的支气管扩张剂中。
