Why controlling the infusion time for tea is important
A Belgian writer I know published a tea book last year, in her book she referred min. 10 - 15-20 minutes infusion time for green tea, and she's referring to the writing by Dr. Servan-Schreiber and Dr. Beliveau. Indeed there are many scentific researches in the world to confirm the prevention benefits of anti-oxidants from green tea; but I have serious worry about having tea infused more than 10-15 even 20 minutes as means for the healing 'treatment' particularly for cancer patients.
If you check on my latest blog, in which I mentioned the taste of long infused tea is very bitter, some green teas might even aggressive to the stomach, which I wonderful how many cancer patients have strong stomach to take it during the chemo treatment period?
One thing I notice from my late Father who was a cancer patient, when he went through the chemotherapy, basically the process caused a lot of problem for his body, for example he couldn't eat but could only drink rice water or soup; he was very weak. I am sured the modern cancer treatment technologies have improved a lot that can ease those painful reactions from cancer patients a lot, but still how to help them to improve the absorbtion of nuitions during and after the treatments should be divided a little bit but not putting them in one basket.
Because I did not read the original research report from Dr. Servan-Schreiber and Dr. Beliveau, so I can not make any judgement about what she's referring to. I do, however, have great deal of concern how that writer referred to Dr. Servan-Schreiber and Dr. Beliveau's writing and suggested the long infusion time for tea without mentioning the importance to make adjustment subject to the physical condition of each patient. The long infused strong bitter taste tea might cause further problem particularily for those who are during the process of taking chemo treatment. May be in the later healing and strengthening phases but again it is subject to the health condition of patient to patient. Even for normal people who have no stomach or intestion problems should learn listening to the body and treat their body, not to mention cancer patients who are in the process of trying to regain their strength.
Personally I try to avoid generalizing the medical benefits, because I believe that's why many scentists in the world are still searching for answers.

that very thoughtful of you to post this. I'm sorry about your father.
-
lanting, I appreciate your concerns. I agree, we aren't all the same and our bodies can't all take the same things and we have to be able to adapt to what works for us. Medicine is still as much art as science.
I personally let my green tea steep for 10-12 minutes. I was told bitterness is caused by using boiling water on green tea and that the water should be just below a boil (or, bring it to a boil, and let it cool a few minutes before you use it). I know my tea never tastes bitter. I don't know if that will help anyone else but I thought I'd pass it on.
-
these are very tough time like stomach problem it will give always heavy pain.i am agree by concern.
-
We only have one body and we only live once. We shouldn't take our body or health for granted, but should learn to listen and to take care of it in time. The taste is somethign that is very individualized decision. Personally I keep remind myself when giving preventive advice to people should first ask about their condition first. The aim is to help people to work 'with' their body/health, but not work 'against'.
-
Whether to boil water or not, subject to type of water, i.e. Ph level, soft or hard. There are different kind of green tea, i.e. steamed or fried, the water temperature and infusion time are differ as well.
Personally when I use +/- 3g leaves with water temperature 80-85 celsius for Sihu Lung Jing, then I will control the first infusion less than 3 minutes, afterwards I gradually enlenghen the infusion time. but when I enjoy Huangshan Maofeng, with abt. +/- 2g and less warm water 80 celsius, then 3 minutes or a little bit longer is fine.
In a day we need to drink min. 1.5L water, which I try to limit the portion of tea to 1L max. Except when I prepare myself some Yansheng Cha based on medicinal herbs with either flowers or herbal leaves.
I like to enjoy different variety of tea so my body will not addict to one specific type.
In 2004, a lady who followed Daoyin Qigong in the Fitness with me was announced for having a very aggressive cancer when her doctor told her, she only has 3 months to live. She came to me for advice during the period when she was receiving chemo treatment, I remember at that she felt tire easily and has very similiar syndroms as my father. I gave her some green tea, Lynzi, and some Chinese medicinal herbs and shared with her the principle of light food and drink;
Most importantly I told her, her life is not something can be predicted or controlled by any doctor, but by herself. I am glad to know when her friend told me recently she's still following my advice and fighting with healthy die, positive thinking and energy. Even though she is not cancer free, but she is still alive today and happily became a grand-mother last year.

Dear Apple. Thanks for your kind thought.
-
Dear Lanting.. thank you for your kind thoughts. I live in Kansas. .. I only have 3 green teas available plus the commercial ones. I very much enjoyed a television show on tea from the Hunan province (area?) of China.
I would appreciate your thoughts on a healthy diet if you would care to share.
-
From everything I've learned, when making green tea, don't let the water boit. If you can watch the water, then stop it just as you see the first bubbles rising up the sides of the pot.
-
Dear LanTing, Thank you for your post. I also like LungJing tea. I love the fresh almost milky aroma when I first pour in the water. What is the "lynzi" tea that you recommend? Is it a kind of mushroom? I am going to China very soon and would like to purchase some.
-
I was also confused about Dr Servan-Schreiber's infusion times. After doing more research, I have decided to continue to steep my tea for three minutes. I use good quality tea leaves and do not contain them in a ball or net while infusing. I also use mostly white tea leaves for increased antioxidants.
-
Dear Apple sorry I only saw the posting today
Concerning the healthy diet, the simple principle that I've learnt from my mother is light taste in food and drink, and we need to learn to adjust type of food we eat from time to time, so when we eat or drink something pure and nature, we keep our body alert. I have to rush for work, but I will post some of my mother's recipes on line later today and this week.
-
Dear Prettyinpink 100,
Lynzi actually is a Chinese traditional medicinal herb mainly from Quizhou region, it looks like a wooden champion. It has very positive healing impacts to our energy in heart, milt, liver, lungs, and kidneys, in other words good for breathing, circulations, dignestion, and immunity system. You have to cook it in water, i.e. 5g : 1L water. Normally I also like to add on some wolfberry (Gugi)
-
Dear Tokyosing, there are few things to decide whether to cook the water or not, i.e.
1. the PH level in water
2. type of tea you drink, i.e. temperature for fine green / white / yellow tea is between 75-max. 85 celsius, then in this case no need to bring the water to boil as you've suggested and it is better to choose Ph level between 6.2 - 7.2; but for Oolong we need the temperature around 95 Celsius then I like to use the water with PH level between 7.2-8
-
Thank you Lanting , I will try the Lynzi. How long do you boi lthe Lynzi in water with the wolfberries?
-
Dear TokyoSing,
Normally I boil Lynzi for about 10-12 minutes then add on wolfberries for another 5 minutes. It is OK even if you boil it longer than 20 minutes. Boil it with small-medium fire. Hope it helps.
-
Here is my mother's recipe for chicken soup:
1. choose the small to medium size of chicken, unskin it (keep the bone). Normally I take one small chicken for the family, if it is just for one person, then I will take the chicken leg.
2. Ingredients: Ginger, green onion, Chinese red date, wolfberries, Chinese Champion
3. After boiled low down the fire and continue to cook for min. 2 hours (the longer the better).
Or you can try to steam it by cover the soup bowl with alu. foil to make sure all flavors are kept in the bowl. (time: 25 minutes)
Just add on some salt and pepper to your taste.
Bon Appétit

I make my chicken soup for colds and flu very simple (family recipe), and with the ingredients that are targeted for the cold symptoms.
For about 12 servings:
- 4 chicken thighs, fat and skin on
- two medium onions
- four medium carrots
- two tablespoons of chopped lovage.
Boil the chicken until the meat starts to fall off the bones. Remove it from soup and set it on a plate to cool off.
Add in the chicken soup pot the onions, peeled, whole, and the carrotts, peeled, whole. Boil until the onion starts falling apart.
Remove the carrot and slice it in 1/2" slices.
While the soup is boiling, start picking the chicken meat. Discard the skin, cartilage, fat and bones, pull the meat with your hands in smaller pieces.
Add the meat to the pot, let simmer for about 3 minutes. Turn off the burner, add the lovage, cover for 5 minutes.
Serve hot.
~~ The chicken meat gives you easy to digest protein necessary to heal, also calcium, magnesium, phosphorus and other goodies
~~ The liquid broth helps re-hydrate your body and also contains the "additives" from the ingredients
~~ the Onion (and the contributionit gives to the soup) is a strong expectorant
~~ the carrots (and the contribution they give to the soup) brings fiber, beta-carotene (which transforms into Vit A and is easierdigested and absorbed when the carrot is boiled whole compared to raw) and falcarinol.
~~ lovage - vitamin A, B and C, micro-minerals, volatile oils, expectorant
-
Dear Day, thanks for sharing.
-
Day... Where do you get your lovage? Do you plant it? does it grow wild? I think I know what plant that is.
-
I grow it myself, it's hard to find in the US. It's mostly a European plant - used in Romania in almost all soups and broths. It has a distinctive fragrance and seasons a soup just perfectly!
I just buy seeds and grow it. Depending on the winter, it sometimes lives from one year to the next. The root can also be used, it's similar to the parsnip.
The leaves are a little big bigger than the parsley. Here's some photos:
Usually in that chicken soup in Romania we also make dumplings, which are different than the American ones. For one, they are made out of cream of wheat, not flour. You take one or two eggs (depending on the size of the pot of soup), separate the yolks and whites, then whip the whites stiff. Add slowly the yolk and cream of wheat until it gets to be like a soft sour cream consistency. Let sit for about 15 minutes (to let the cream of wheat "fluff") then start putting in the very slow simmering pot about 1/2 teaspoon of the composition (they "grow" a lot when they boil a 1/2 tsp makes a tablespoon-size dumpling). When they are boiled, they rise to the top. Make sure you turn them ove to make sure they are well boiled.
This is how it looks
-
thank you Day - that looks awesome. I cook a lot and love farina (cream of wheat). I can't wait to try the dumplings. The cream of wheat is dry when you add it with the yolks to the eggwhites? If I were to use 2 eggs, approximately how much cream of wheat would I add? 3.4 cup?
Now I recognize lovage.. I know exactly what it is.. I've seen seeds and my Russian friend grows it. People grow and sell it in Kansas City. (you should see the awesome Vietnamese farmers we have at out city market and the wonderful vegetables they grow.)
I make several recipes for chicken soup for my family. (chicken soup days are almost over).
-
Dear Lanting, Thank you for your recipes. I was travelling the last few days. I will try the lynzi as soon as I get back home.
-
This is turning into an interesting thread. I read with great interest, about a tea grown in the southern part of the orient called Jiaogulan. It is difficult to find, even with our excellent array of oriental stores here in the midwest.. I am going to try and grow it this year. It is sold as 'anti cholesterol tea in some stores.. it's quite tasty.
I will look for Lynzi at the stores. I've seen the red dates.
-
Indeed I really enjoy the conversation and information sharing from all of you.
Jiaogulan is quite tasty, it contains no coffeine
, the biochemical structure is quite similiar as Ginseng and it cost much cheaper, so it has another name " Ginseng for normal people". Many health benefits, including lowing down calorie, cholesterol, preventing the growth of cancer cells, fighting against Peptic ulcer, accelerating energy and calming. It taste sweet, so when I prepare tea from it, I normally put it in the bag and follow the same infusion time as for Oolong tea.
Tne red date can only used in the chicken soup, and it tastes GOOD.
-
I certainly do not expect any sort of cure from Jiaogulan... but am very interested in having a steady supply.
Why can the red date only be used in chicken soup lanting - is it a dried date?
-
apple - it all depends on the size of the eggs. Anywhere from 2/3 cup to 1 cup. It has to have the consistency of a soft custard when you let it sit, and it gets harder as it sits and the cream of wheat swells.
-
Dear Apple, Jiaogulan do have some medicinal effect when taking in a longer period particular in the post healing phase what and how to maintain healthy diet is very important.
Chicken soup is not the only recipe for red date, but it is a typical soup recipe that my mother used to cook since I was kid.
You can use red date either in tea (which you need to cook it for about 5 mintues, because it's dried), in soup or in stow pot. You can even use it in the dessert but you need to soak it in water for few hours till it's soft again, then remove the seed and then either cut into small pieces, otherwise can only blend with other fresh fruit to have a energy drink.
-
I drink organic green tea from the health store religiously a couple of times per day on a regular basis. I usually let it steep for about 5 minutes.
-
Dear Charmaine, Don't know what kind of organic green tea you bought from the health store. Normally at work I only take about 2g (or less), so I won't have to worry about the longer infusion time and I can make tea few times from it till the taste is gone.
When I am seriously enjoying the tea in the evening or after meal at home, then I follow the 1:50 with shorter infusion time.
-
Hi Lanting, what green teas do you like? I personally like Lungjing and a Tie guanyin that has a fresh almost grassy flavor. The only problem with these delicate teas is that if you steep them too long, they turn bitter.
