Nigel at Teacraft Laphet or pickled tea leaves, as you mentioned, are indeed a favourite appetizer in Myanmar (as in other Asian countries). The Burmese are suffering from extremely high rates of fluorosis since not only the tea, but the water used in the processing of laphet is chock full of fluoride (and ascenic). You may have not seen these effects since these tend to be rural peoples who use deep well water for irrigation, pickling and to make tea as a beverage. UNICEF and WHO have made these areas (high fluorosis) a serious focus for birth defects and other fluorosis supported health problems primarily affecting women and children. My point is simple: here in the states we have a lot of fluoride all ready in our tap water and we get it in our liquid teas, I think it's enough. This is my personal opinion. Shen |

and I'd still worry about kidney stones. Very high concentrations of
calcium oxalate in tea leaves. Milk will bind to the oxalate rendering it harmless, but studies show milk also prevents most positive tea-related health benefits. I wouldn't chew the things personally. My dad drank green tea for years and had the most terrible kidney stones.. wouldn't want to go through that. (I still drink lots of greens though) |

Shen Shen, come on, a tiny leaf or two is just a little treat not an obsession... Jenn I tend to be conservative when it comes to well-being. I've seen too many (American) patients who go waaaay overboard with any new food or supplement trend - i.e. soy. A bit does some good; too much can be disastrous to your health. Green tea is a new fad food. It's in everything from yogurt to nail polish. I agree that moderation in anything generally works well. I don't mean to sound cranky; but, I also have a great distrust (an old hippie) of the quality and quantity of fluoride that readily available in foods, dental care and the water supply. I'd just rather err on the side of caution. Shen |

There are inummerable sites with fluoride alerts all over the web. Check WHO, Unicef, American Journal of Medicine, the National Library of Medicine, the National Academy of Sciences, U.S. Dept of Health and Human Services and on and on.................if that's too much work, just do a search on "fluorosis and osteosarcoma". Fluoride threatens bone health. It's also in cigarettes, cereal, soda pop, and anesthetics. You're the one who doubts the problem. You look. I've spent the last 20 years in practice. And a hell of a lot of medical education prior to that. As I said earlier - do what you want. However, I would never encourage anyone to chew on tea leaves. Chewing on anything repeatedly or excessively to suck the flavour out of it doesn't do much for TMJ either. Enough said. That's all I have to say about chomping on leaves. Shen |

"You're the one who doubts the problem. You look."
thanks, thats helpful, and i dont doubt that fluoride impairs bone formation, i doubt that its this big deal youre making it out to be. from the looks of it, most people in China and on this group already have fluorosis ...so yeah, im sure its a problem. smokers dying of lung cancer, im sure their concern is fluoride content. children with inadequate nutrition and so inadequate bone growth, im sure fluoride will fix the problem NOT taking care to eat enough, healthy and nutritious. |

Hi all,
On this flouride issue, can anyone say about the health of the people who drink whole leaf, like matcha? Does this little tea leaf have the effects of the other tea when it is consumed daily or several times a day? I have read that all the tea leaves are ground and used in this yummy beverage. I have heard that powdered green tea leaves are used in cookies, ice cream, tea supplements like green tea capsules, and green tea smoothies or lattes. What do you think is a safe amount of this form of tea? Jenn |

Some day I will come to you for permission to use your article, if you don't mind. I have documented a case study of green tea fluoride he The person involved sounds really extreme, but it is probably this is probably most serious risk of over-consuming green tea (other than green tea extract), compounded by the low quality of bottled green tea. Green Tea and Fluoride http://www.amazing-green-tea.com/flu...green-tea.html As for kidney stones, the scientific evidence is mixed. This are the studies I can find to date. I think each person has to make their mind up on this one. Green Tea and Kidney Stones http://www.amazing-green-tea.com/gre...ey-stones.html I haven't tried chewing tea leaves.The Chinese tea experts are generally against it. They haven't got any studies to back up their claim. Apparently a lot of unhealthy substances are locked up inside the leaves that are not released in brewing. When when you chew, or over-brew, these bad stuff are more likely to come out. Put it another way, brewing is far healthier and enjoyable than chewing. I don't think it is deadly, as Nigel kindly pointed out, but sometimes it is worth listening to these centuries old folk wisdom. Julian http://www.amazing-green-tea.com |

Just one or two tho. And whitetealike silver needles was my most favorite Jenn PLEASE STOP CHEWING YOUR TEA LEAVES!!!! I am assuming you are in the states or in another "westernized" country. Fluoride is in your toothpaste and in your drinking water. This is generally natrium fluoride. Fluoride in tea is generally calcium fluoride. Fluoride is VERY present in tea leaves! Fluoridosis is a disease of over-consumption of fluoride that destroys bones and teeth. The more EGCG in tea the lower the fluoride; however, it's still in there. The American Journal of Medicine in its January issue carried a study from the FDA (this study continues) measuring fluoride in instant teas that are commercially used for "iced tea". Since the USA is the world's largest consumer of these teas, they initiated this study which is now measuring fluoride levels in most widely used teas. The results in these instant teas were very high - up to 6.5 parts per million. Drink your tea. In my opinion, the benefits outweigh the hazards unless you're doing several gallons a day. If your chewing tea leaves as one would tobacco, you might want to say good-bye to your teeth and perhaps your jawbones, as well. This is just my personal opinion. Thank you. I am concerned about fluoride. Two things that may make me safer a 1. I don't use toothpaste with fluoride. 2. I live in Maine, and we do not get our water from a public water source (we have an artesian well). Still, moderation in tea leaf ingestion is the right way to go. On days I chew tea leaves, I do not drink the infusion. (I would get too much caffeine if I did.) George |

[...] I am concerned about fluoride. Sorry, I should've brought this up earlier in the thread, but it just occurred to me. While I don't know anything that makes me alarmed about this, it is widely accepted that the tea plant takes up an unusually high level of aluminum from the soil, and aluminum seems to have no role in the body. If you eat lots of leaves, you'll certainly take in considerably more aluminum than you would from tea liquor. But, as I said, I'm not panicking. From the limited amount of medi-browsing I've done, it may well be true that all the aluminum we take in gets harmlessly excreted. /Lew --- Lew Perin / http://www.panix.com/~perin/babelcarp.html |

Hello George If you send me a quick email I will send you all the info bout the silver needle I have off line... Jenn The only tool available to a tea man to decide the process chain on a particular green tea leaf standing on a bush in the field is his mouth and its unlimited capacity to analyse everything present or contained in tea.
