Protective effect of Lycium barbarum on the cancer drug, Doxorubicin-induced Cardiotoxicity [1]

Caution:

禁忌﹕

Not to use in cases external heat, (like cold or flu,  swelling with inflammation), spleen deficient (pixu) with dampness and loose stool or diarrhea.

An increased INR value was noted with concurrent use of warfarin and qi zi.Thus, combination of L. barbarum L. and warfarin should be avoided.  [1]

外感實 熱﹐脾 虛濕滯及腸滑便溏者忌服。

發現與華佛林（warfarin) 同用 INR 值會增高。所以两者不應同用。[1]

Quality:

品質鑒別﹕

The better quality qi zi is from Zhong Ning Area.

 Quality identification:

1. Shape: oblong--not round--but not thin.

2. Color: red or purplish red except for petals.

3. Petal area: obviously white. If artificial color has been added, the areas where the petals are will be tinted. Artificial coloring is a sign that the seed is of lower quality. Artificial coloring can be toxic.

4. Dryness: the water content should be about 12% to !3%. The seeds should not lump together. Test for dryness by  squeezing them together and then releasing pressure.  Good quality seeds should not lump together; they should become loose when the pressure is released.

5. Taste: sweet. The seeds should not taste acrid.

6. Smell: the smell is fragrant once the package is opened.

7. Sinking test: When dropped into water, the seeds should  float for sometimes and should not sink in a short time.

8. Watch for glister under the sun. It can be residue of alum or sulfur that has been sublimated from smoking where most sulfur has turned to sulfur dioxide and a small portion can be sublimated to the fruits. If alum has been added the herb feel coarse and dry to touch, and will taste tart or/and sour by licking the herb.

National Quality Inspection Agency of China has banned the use of sulfur dioxide to preserve the fruit.

Addendum:  Carefully examine under the light to see if there is white crystal powder . If so, it may be soaked in alum water (harmful to health); or smoked with sulfur. The white powdery crystal may be the sublimation of sulfur or the residue of alum. If the berries have been soaked in alum water, they feel stiff and the taste can be sour, astringent. The side effects of alum (aluminum potassium sulfate) are osteoporosis, bone loss and memory loss.
To shorten the drying time, some small farms often use saturated alkaline water to soak the berries before drying. These processed berries seem to be bright red in color and very attractive, but their nutritional value can greatly reduced. Alkaline treated berries possess a bitter taste

In China, gou qi zi from Ningxia province is considered the best. There are merchant selling Xizang （Tibetan) gou qi zi and Xinjiang gou qi zi as Ningxia gou qi zi to fetch better prices.

 中 寧枸杞辨認七法：
中寧枸杞已被引種到全國十五個省市自治區，但無論引種到何方，均由於缺少中寧所特有的種植枸杞子的土壤條件和地理環境，使中寧枸 杞同其他引種產 區生產出的枸杞產品外觀及營養成份含量上有明顯的區別。
看果形：中寧枸杞呈橢圓扁長而不圓，呈長形而不瘦。
看果臍：中寧枸杞果臍白色明顯。
看頗色：顏色呈紅色或紫紅色。
看結塊：中寧枸杞乾果含水量在12％-13％之間，包裝不結塊，就是擠壓成塊，失壓後能 自動鬆散。
試下沉：中寧枸杞放入清水杯子中在短時間內不下沉。
品味道：中寧枸杞皮薄肉厚，口感純正，甘甜，無苦澀味和其它異味。
聞氣味：凡是中寧枸杞一旦打開密封的包裝就有一般特殊的香味。

中寧枸杞子辨認资 料来源：摘自“美食導報”2002﹐11﹐15

國 家 質 檢 總 局 嚴 禁 用 硫 磺 加 工 。

補充﹕在 光照下，小心察看杞子上有無附著白色的結晶。那可能是浸過明礬水(對健康有害)﹔或是熏硫磺時﹐部份硫磺昇華結晶 於杞 子上。 浸過明 礬水的﹐觸 手會有僵硬﹐乾澀的感 覺﹔ 如輕舔藥材表面，會有酸﹐澀的味道。明礬 （硫酸鋁鉀(鉀鋁礬))的副作用可使鈣質與磷質流失而導致骨骼疏鬆，記憶減退。

為了縮短晾晒時間，有些小農場往往用超飽和的濃鹼水 浸泡枸杞，然後再加晾晒。這樣處理過的枸杞看來色澤鮮紅，十分誘人，但其營養萬分已大大降低。用鹼水處理過的枸杞有苦澀感。

有些藥商把價錢較便宜的西藏枸杞子與新疆枸杞子當作寧夏枸杞子賣，以取得較高價錢。

看關於二 氧化硫處理過的乾貨。
