Echinacea is an herb that is native to areas east of the Rocky Mountains in the United States. It is also grown in western States, as well as in Canada and Europe. Several species of the echinacea plant are used to make medicine from its leaves, flower, and root. Echinacea was used in traditional herbal remedies by the Great Plains Indian tribes. Later, settlers followed the Indians' example and began using echinacea for medicinal purposes as well. For a time, echinacea enjoyed official status as a result of being listed in the US National Formulary from 1916-1950. However, use of echinacea fell out of favor in the United States with the discovery of antibiotics. But now, people are becoming interested in echinacea again because some antibiotics don't work as well as they used to against certain bacteria.

Echinacea is widely used to fight infections, especially the common cold, the flu, and other upper respiratory infections. Some people take echinacea at the first sign of a cold, hoping they will be able to keep the cold from developing. Other people take echinacea after cold symptoms have started, hoping they can make symptoms less severe.

Echinacea is also used against many other infections including urinary tract infections, vaginal yeast infections, herpes, HIV/AIDS, human papilloma virus (HPV), bloodstream infections (septicemia), tonsillitis, streptococcus infections, syphilis, typhoid, malaria, ear infection, swine flu, warts, and nose and throat infections called diphtheria.

Other uses include anxiety, low white blood cell count, chronic fatigue syndrome (CFS), rheumatoid arthritis, migraines, acid indigestion, pain, dizziness, rattlesnake bites, attention deficit-hyperactivity disorder (ADHD), and improving exercise performance.

Sometimes people apply echinacea to their skin to treat boils, gum disease, abscesses, skin wounds, ulcers, burns, eczema, psoriasis, sun-related skin damage, herpes simplex, yeast infections, bee stings, snake and mosquito bites, and hemorrhoids.

紫锥花最早源自于北美地区，当地印地安人也是最早认知紫锥花保健功效的民族。他们当下充分挖掘了紫锥花的功效，用来滋补强身、增强体力。1870年代左右，一位德籍医生在北美行医，不慎被毒蛇咬伤，而亲身体验紫锥花的神奇功效的他意识到这是这朵优雅的小花其实是不可多得的宝贝，于是医生研制出了紫锥花酊剂，自此，紫锥花开始在美洲大受欢迎，并在1930年代引进到欧洲，成为欧美第二大保健植物。

这朵花不仅有故事，还有丰富的内涵。紫锥花具有机能性的成分包括酚酸、多醣体、烷酰胺、聚乙烯、醣蛋白等，其中酚酸、多醣体和烷酰胺是研究的重点，和调节免疫系统有很大的关联性。

同时，紫锥花可透过免疫系统促进淋巴细胞活性，因此可预防感冒，并改善感冒症状和缩短病程。早在2000年公布的一个双盲研究表明，在感冒初期使用紫锥花茶，可有效改善症状并减少感冒日数。此外在另一项由一百二十位已出现初期感冒症状者所进行的研究中，更发现紫锥花可避免感冒症状发展成「真正的」感冒 ，达到「停止感冒」的效果。

紫锥花可以在服用后快速刺激免疫系统的作用，使人体对抗病毒的能力在最短时间内被提升，因此紫锥花并不像一般的健康食品，必须长期中低剂量不间断的服用，而是在「必要」的情况下才补充。一般感冒大约只需连续服用五至七天即可。但如果已连续服用两周，则必须至少停服一周之后再续服，才能发挥最佳的免疫提升效果。

试一试来自加拿大的Total Natural紫椎花胶囊吧！流感季节或者换季时它可是抗病神器，服用一个星期后，就会出现明显效果，有助于防止肺和喉咙，与普通感冒相关的感染。

同时它还适用在任何微生物感染（如阴道念珠菌感染、口腔泡疹病毒感染、细菌性肺炎、眼部披衣菌感染等）的辅助治疗上，即使患者已在使用抗生素之类的杀微生物制剂，服用紫锥花萃取物仍有缩短疗程、加速痊愈的作用。

大病小病，坚决不给趁虚而入的机会！

维生素在我们身体中扮演着很重要的角色。经常会碰到小伙伴咨询关于维生素的问题。那么，维生素到底是什么呢？是维生素A，维生素B，或者其他吗？它又是怎么定义的呢？一起来看看吧～

维生素

维生素（英语：Vitamin）是一系列有机化合物的统称。它们是生物体所需要的微量营养成分，而一般又无法由生物体自己生产，需要通过饮食等手段获得。

维生素不能像糖类、蛋白质及脂肪那样可以产生能量，组成细胞，但是它们对生物体的新陈代谢起调节作用。缺乏维生素会导致严重的健康问题；适量摄取维生素可以保持身体强壮健康；过量摄取维生素却会导致中毒。

维生素的分类

维生素分为两种，水溶性维生素和脂溶性维生素。人体一共需要13种维生素，其中包括4种脂溶性维生素（维生素A，D，E，K）和9种水溶性维生素（8种维生素B，维生素C）。

水溶性维生素特点

①水溶性维生素可从食物及饲料的水溶物中提取。

②除含碳、氢、氧元素外，多数都含有氮，有的还含硫或者钴。

③B族维生素主要作为辅酶，催化碳水化合物、脂肪和蛋白质代谢中的各种反应。多数情况下，缺乏症无特异性，而且难以与其生化功能直接相联系。食欲下降和生长受阻是共同的缺乏症状。

④B族维生素多数通过被动的扩散方式吸收，但在饲粮供应不足时，可以主动的方式吸收。维生素B12的吸收较特殊，需要胃分泌的一种内因子帮助。

⑤除维生素B12外，水溶性维生素几乎不在体内贮存。

⑥主要经尿排出(包括代谢产物)。

脂溶性维生素特点

“脂溶性维生素”易溶于非极性有机溶剂，而不易溶于水，可随脂肪为人体吸收并在体内储积，排泄率不高。每一种维生素通常会产生多种反应，因此大多数维生素都有多种功能。

什么人更需要补充维生素？

一般的成年人如果在营养摄入均衡的情况下其实是不太需要额外补充维生素的，但是有一部分特殊人群他们因为身体上的能量消耗比较大，容易导致某些营养的缺失，需要适当的补充一些维生素来保证身体的健康，如吸烟人群，孕妇以及老人。

其中老人可以说是最为庞大的需额外补充维生素的群体了。超过50岁的人群由于上了年纪，身体上会出现大大小小的毛病。中老年人随着年龄的增加，很多器官都会出现老化，新陈代谢也会变得缓慢，所以应该适时的全面补充各类维生素来保证身体的健康。

Total Natural的ABC老人综合维生素片中含有老人日常所需的维生素，其中包括维生素A、维生素C、维生素E、维生素K1、维生素B1、B6、B12、钙，锌等主要成分。

采用独特的配方，让补充的营养能最大可能性的被老人快速吸收，每天只需服用两次，每次一片即可，让长辈们安心的享受健康生活吧！

We all want more energy, protection from disease, and an aid to help us reach our healthy living goals. We get these benefits from consuming vitamins in various foods, but can we get the same benefits from a vitamin supplement or are we putting our health at risk by using them?

If you're in general good health and eat a variety of nutrient-rich foods from all of the food groups, then you should not need vitamin supplements to meet your nutritional needs. However, some groups of people gain substantial benefits from supplements. For example, vegans completely avoid animal products. These individuals would need to supplement their diet with vitamin B12, because B12 is only found in animal-based foods, such as meats, poultry, fish, eggs and dairy products.

Older adults can also benefit from dietary supplements that contain vitamin B12. One reason is the high occurrence of atrophic gastritis, which is a condition characterized by an inflammation of the stomach lining. The inflammation interferes with stomach secretions, which are needed to free up B12 so it's available for absorption. Dietary supplements of B12 are easier to absorb than B12 obtained through foods, helping a person with this condition obtain what they need.
