扶桑花茶


扶桑花茶,對於保持健康的膽固醇與血壓是優質的選擇。扶桑花是大受肯定的藥草,通常長在全球熱帶地區,最早在安哥拉被發現。迷人的香氣讓它經久廣受歡迎,遍布在北非、中東、甚至歐洲,也是夏威夷的州花。

雖然印度原住民喜歡吃它乾燥的葉子,當成蔬菜進食。大部分的人喜歡泡茶喝。事實上,大部分的茶剛好都含有扶桑花。是天然的抗氧化劑,也有抗膽固醇的特質,但最重要的是能有效降低血壓。某些重要的植物鹼類,槲皮素,以及花青素,後者似乎最有影響。扶桑花,基本上從很多的研究顯示出在心血管方面的奇蹟。可以打開血管,減緩血管收縮激素的釋放。

對於治療中度輕度的高血壓有很棒的效果,2007年一項研究顯示,給參加者250mg劑量的乾燥扶桑花粉,血壓保持在健康的水準。

研究顯示扶桑花茶能降低血壓

2010年美國的營養學研究報告裡,想要知道扶桑花對於輕度高血壓是否有抗高血壓效果。65位年紀在30~70歲之間的自願者當中,飲用(文中沒提怎樣的形式)六周。與安慰劑效果比對,扶桑花萃取在收縮壓從頭就較高的人當中,似乎更勝一籌。

另外一些在2007所做的測試裏頭,扶桑花有讓膽固醇正常化的能力。42位參與測試的人,在幾個禮拜內給予不同劑量的扶桑花萃取。研究者發現為了讓膽固醇保持在健康水準,最有效的劑量是一天三次,每次1000mg的劑量。

另外一項研究,大部分是女性,總共60位參加,科學家要比較紅茶跟扶桑花茶的效用。雖然主要目標是要研究血糖值,但一個月後,他們發現扶桑花對於LDL低密度脂蛋白(不好的膽固醇),HDL高密度脂蛋白,以及整體膽固醇能保持在一個健康值,扶桑花對於這三個數值能全面表現出功效。而紅茶只能正面反映在HDL高密度脂蛋白。

Hibiscus tea is excellent to maintain healthy cholesterol and blood pressure levels
(NaturalNews) Hibiscus is a greatly appreciated herb that usually grows in tropical areas around the globe. It was first discovered in Angola but its pleasing taste has become very popular through time amongst the North African, Middle Eastern and even European populations. It just also happens to be the state flower of Hawaii.
Although natives of India like to eat its dried leaves as if they were eating vegetables, most people prefer to make teas out of them and as a matter of fact, most teas happen to include hibiscus. It's a natural antioxidant that also has anti-cholesterol properties, but most importantly it can effectively lower blood pressure. Some of its most important alkaloids are quercetin and anthocyanins, with the latter seemingly having the most impact. Hibiscus has basically shown through many studies that it can work wonders with the cardiovascular system by opening the arteries and slowing the release of blood vessel-constricting hormones.

It seems to work exceptionally well with cases of either low or mild hypertension. A study from 2007 showed that by giving participants consistent doses of 250 mg of a dried powdered hibiscus extract, blood pressure was maintained at healthy levels.

Research shows that hibiscus tea can lower blood pressure
In 2010 the Journal of Nutrition reported on a study that took place in the US with researchers aiming to find out if hibiscus had antihypertensive properties when confronted with mild cases of high blood pressure. Sixty-five individuals between the ages of 30 and 70 volunteered to take part in the trials for a period of six weeks. When compared with the placebo, the biggest change occurred with systolic pressure levels. Regardless of age, the hibiscus extract seemed to have a greater impact with individuals having higher systolic levels from the start.

Some tests done in 2007 showed hibiscus has the ability to normalize cholesterol levels. Forty-two individuals were given various doses of hibiscus extracts during a few weeks. Researchers noted that in order for cholesterol to remain at healthy levels, the most efficient dose hovered around 1000 mg being taken three times per day.
In a study that mostly included women out of a total of 60 participants, scientists were able to compare the effects between black tea and hibiscus tea. Although the main goal was to study blood sugar levels, after one month they realized that hibiscus was responsible for keeping LDL, HDL and the overall cholesterol at healthy levels. While hibiscus was effective across the board, black tea only positively influenced HDL levels.
