Shih) Gastrodia rhizome (Tian ma 天麻) Each year, during public examination times, various claims that gastrodia can help improve test scores fly high. Is there any validity to these claims? Experiments done by the China Medical College's Research Institute have shown that gastrodia (tian ma天麻) can improve cognitive abilities and remedy study and memory disabilities. Besides the cognitive benefits, gastrodia can also delay the onset or slow the progress of Alzheimer disease and other aging related neuro-disorders. So, what is gastrodia? - a functional food or a medicine? Gastrodia is a very unusual plant. It contains no chlorophylls and therefore is not green in color. Lacking chlorophyll, it cannot produce nutrients through photo-synthesis as most plants do. Moreover, Gastrodia has no roots; what's in the ground is a rhizome (tuber) that appears sealed shut from the soil environment. If so, how does it get nourishment and grow? Gastrodia is entirely dependent on a soil fungus, Armellaria mellea, for its nutrition. This fungus can develop into the fruiting body commonly called "honey mushroom(蜜環菌)" While Armellaria destroys trees and potato crops, it does not appear to cause any harm to gastrodia; to the contrary, it feeds it. While it is evident that gastrodia benefits from being parasitized by Armellaria, it is unclear what benefit Armellaria gets from gastrodia. The genus Gastrodia is found in warm climates, for example, in Madagascar, tropical Asia, Oceania, Japan, and China. It consists of just 20 species, five of which are found in China, the main one being Gastrodia elat (tian ma). The Chinese herb is produced in the YunNan, GuiZhou, Tibet, and Szechuan provinces (雲,貴,藏,川); the rhizome (tuber) is the part used. Gastrodia was mentioned by Ge Hong (葛洪), a medical and Dao (道) writer, in his book BaoPu Zi (抱朴子) as Ding Feng Cao (定風草). NeiJing (內經) has stated that "wind (feng 風)" causes dizziness and its five element property belongs to the "wood" system. Wind is a metaphor for speed, symbolizing diseases that can happen suddenly and progress very fast with no visible wounds. Traditional Chinese medicine classifies this type of illness as "wood" and says this type of illness belongs to the "liver system." The liver meridian starts from the toe and runs all the way to the head. When the liver "wind" ascends and does not descend or when the liver "fire" flares up, the face and ears will turn red, indicative of high brain pressure; most of the brain disorders are related to the liver meridian. "Ding Feng" means "to stabilize or calm the wind." That is why gastrodia can help prevent or release discomfort caused by "wind" such as dizziness, black eyes, headache, convulsions and spasms, numbness and paralysis; all of which are symptoms caused by brain blood vessels deterioration and stroke. Gastrodia is called "ding feng cao", that means it is an herb that can calm the wind. The fact that gastrodia benefits the cognitive function and can help slow down the onset of brain diseases caused by aging is supported by modern pharmaceutical researches. What is a safe and effective way to use gastrodia? For use in medicine, gastrodia is often mixed together with other herbs in herbal formulas and in high dosages. These medicines should only be taken with professional advice. Toxicology study with laboratory animals has found that animals developed side effects such as weakness, lack of energy, lost of appetite, and weight loss after injections of over 1 gm. of extract per kg. of body weight. To use as a functional food or food supplement, it is safe when used alone and at low dosage. A dosage of less than 5 gm. a day, stopping for a week after a week of consumption is a good safe guideline. It is even safer if only taken once a week with dosage of 3.78 m. To prepare, simmer 3.78 gm of gastrodia with 5 lotusds seeds in water. Drink the tea as a good functional food for the cognitive function. Ganoderma lucidum (Ling zhi 靈芝) Ganoderma lucidum, whose literal translation from Chinese is miraculous mushroom, has many legends, probably because of the word miraculous in its name. It was said that ganoderma lucidum grew in really high mountains and cliffs that were difficult to get to. It is true that ganoderma lucidum is rare and hard to come by in nature, but the conditions to grow ganoderma lucidum are no different from the conditions used to grow ordinary mushrooms: a hot and humid environment. Other than our imagination, what is so miraculous about ganoderma lucidum?
Laboratory animal and cell researches have shown ganoderma lucidum to be effective in helping various functions and subsystems of our body: the central nervous system, automatic nervous system, respiratory system, cardiovascular system, hormone system; the metabolic process, liver and the detoxification process, the controlling of hypertension, the contraction of the intestine muscles and the uterus muscles, and the protection of our body from radiation. Clinical studies are still ongoing to establish qualitative and quantitative measures of effectiveness.
There are more than 300 different types of ganoderma lucidum in record. Traditional Chinese medicine has recorded the green, white, yellow, red, black, and multi-colored variants. Out of all these, the red variants and the purple variants have the most documented effectiveness in clinical records. Recent research found that the spore of the mushroom is the most effective part of the ganoderma lucidum. The mushroom body itself is difficult to use and it takes a long time to extract the useful ingredients from it. It is also difficult to control the concentration and standardize on the dosage. The active ingredients extracted and isolated from ganoderma spores are: ganoderma polysaccharides, ganoderic acid, lucidenic acid, ganoderma acid, and ganodosterone oleic acid.
According to the Pictorial Guide to Chinese Medical Plants (中國藥植圖鑑), ganoderma lucidum can help relieve neurasthenia, insomnia and digestive disorders. BenCaoGangMu (本草綱目) says ganoderma lucidum heals weakness and fatigue; other traditional Chinese medicine classics record ganoderma lucidum as useful in treating respiratory diseases such as bronchitis, coughing and whizzing. So what is the relationship between ganoderma lucidum and calming emotions and improving cognitive functions? Modern lifestyles are very busy and stressful. Neurasthenia, insomnia, lack of concentration, and lost of memory can result from stress and thinking too hard when the brain is not provided with adequate rest. What's happened is that we lose our ability to handle stress. The normal reaction to stress is "fight or flight." Stress become problematic when one cannot win the fight and cannot flee; causing both physical and mental fatigue. The most effective means to combat stress is to improve and enhance one's immune system. This is what's miraculous about ganoderma lucidum. From clinical studies, ganoderma lucidum helps the body adjust to the pressure situations and enhance the immune system. According to traditional Chinese medicine classics, the property of ganoderma lucidum is neutral and the taste, sweet. In reality, it tastes bitter, and has only a very slight taste of sweetness. Most people will add sugar to sweeten it, not knowing that sugar is actually harmful to neurasthenia patients. The best way to prepare ganoderma lucidum is to simmer the spores or the mushroom in water. Since it is not easy to extract the active ingredients from ganoderma lucidum, we recommend simmering it with water for at least five to six hours. After that, turn up the heat to reduce the liquid for easier storage. You can dilute it with water again before use. Each time consume quantity equivalent to about 3.78 gm of ganoderma lucidum. ♁
加州Kaiser醫院負責患者教育與健康的主任Dr. David Sobel說: “走進現代的超級市場, 您在三分鐘之內所看到各種高熱量、高油脂的食品要比我們祖先一輩子所看到的都多。“ 大量的速食與不耗體力的娛樂所造成的不健康生活方式, 衍生出各種慢性病。 Brigham Young 大學生活方式醫學教授Steve Aldana博士說: “我們的健康醫療系統還不如說是疾病治療系統。” 因其著重在治療而非預防。結果是:雖然治療方式不斷擴充,美國慢性病患日增。 從1997年至2004年,第二型糖尿病患增加百分之五十,心臟病率也在上升。 主要是由於二次大戰後出生兒的老化,不過35歲以下死於突發性心臟病的人數也增加很多。 照目前趨勢來看, 當今兒童可能是近代史中第一次平均壽命比父母要短的一代。 美國人必須認真檢討生活習慣,才有可能扭轉趨勢。 根據美國營養協會2005年三月期刊中的一項研究:持續六星期的健康飲食並每天運動30分鐘,使170位中老年人大大降低得心臟病、 糖尿病、及癌症的風險。 許多研究指出: 對患者而言,改善生活方式所得的效果不亞於服藥―對第二型糖尿病患: 減輕體重、多運動;對高血壓患者: 採用防止高血壓食療法〈DASH, Dietary Approaches to Stop Hypertension〉;膽固醇高者: 攝取有益心臟的食品―其降血糖 、降血壓、 降膽固醇功效與藥效不相上下。健康的生活方式比任何藥物或醫療更能預防疾病、 殘障、早逝。以下問題將幫助您回想一天中所攝取的飲食及所參與的活動,藉此尋求增進健康的生活習慣。
如果睡眠充足,而白天仍然感到疲倦,則必須請教醫生;可能是因為藥物副作用或健康出問題,譬如Sleep apnea,一種容易引起心臟病發作及中風的呼吸失調症。在燈光充足的地方工作、出去走走、或乾脆睡個午覺,短短的十五、二十分鐘的身心放鬆,就可以提高整個下午的工作效率。 如何培養開朗的心胸? 〈1〉將心念專注於美好的回憶,〈2〉參與您喜歡的活動,〈3〉每天積極地與自己的心靈溝通,看清事物浮沉,如果您的負面情緒影響到日常生活的運作,就必須請教專業人士。 肥胖不僅與糖尿病或心臟病有密切關係,而且可能是僅次於吸煙的致癌因素。一項針對900,000成人的調查發現:約14%男癌症患者,20%女癌症患者有肥胖症。哈佛大學2005年的分析指出只要減輕5到20磅即可降低10%的得癌率。
自2006年1月1日起,美國食品藥物管理局〈FDA〉規定所有食品標示必須列出變性油脂的含量。新的研究發現:變性油脂會增加身體發炎的危險性。發炎是身體免疫系統對感染或受傷的反應,過度或長期性的發炎會損害動脈及其他結構, 容易引起心臟及其他種病症。 哈佛大學的研究指出:用於烘烤及速食的變性油脂〈氫化過的植物油〉會增加健康者的發炎指數〈indicators of systemic inflammation〉。在最近的美國臨床營養期刊中,同一組研究員發現對心臟衰弱的人,變性油脂會使其發炎情況惡化。其他的研究顯示變性油脂可能比飽和性油脂還糟:此兩種油脂都會使壞膽固醇〈LDL cholesterol〉增高,但變性油脂還會降低好的膽固醇〈HDL cholesterol〉。 營養專家建議每天變性油脂及飽和油脂的總量不要超過所有卡路里的十分之一。〈以每天2000大卡為例, 不要超過22公克〉。根據哈佛大學的研究:對心臟衰弱的人而言, 避免攝取變性油脂是非常重要的。如果食物標示尚未列出變性油脂的含量,若成份中含氫化油脂, 就表示該物含變性油脂。 譯者附註:零加零不等於零, 如果食品中,每份〈each serving〉的變性油脂低於0.5公克,美國食品藥物管理局〈FDA〉 准許標示以零計。消費者要仔細察看成份是否含氫化油脂。也有很多廠商以飽和油脂取代變性油脂,而強調"零變性油脂"。不要以為不含變性油脂就可以放心食用。而是要看變性油脂、飽和油脂及膽固醇三者。變性油脂多存於油炸物、甜甜圈、糕點、加工食品〈速食麵、冷凍食物、餅乾、馬鈴薯片、玉米片等〉。 (有關變性油脂訊息可查看FDA 網站)
秋高氣爽之際,朋友間常問:食療上該注意些什麼?在此,我們特別轉載第七期通訊的〈四季食療:秋季食療〉與大家分享。 秋天氣候乾燥,所謂秋高氣爽,表示空氣中的相對溼度降低,尤其在北美洲的某些地區,對於年紀大的長輩容易產生肺燥的現象,引發呼吸系統的毛病,食療的重點在於平補,以潤為主,避免太涼、太熱的食物。
