Chinese Black Vinegar

Growing up, I was never fond of anything sour.  Cane vinegar, tamarinds, you name it, I hated it.  However, things changed in 1999.  That was when I went to Israel for the first time and discovered that I liked the lemon based seasonings used in some vegetable dishes there.  (Regretfully I forgot the name.)

The second major paradigm shift (not total – I’m still not a sour person) happened when I lived for almost a year in Nanjing in 2005.  It was there that I fell in love with Chinese Black Vinegar.  It was good with dumplings, it was good with soups, heck, it was good with everything.  Also, it got rid of the saltiness inherent in Nanjing food ha ha.

My relatives and friends noticed the difference when I came home.  Suddenly I’d put Chinese Black Vinegar on almost everything.  I also found it pleasantly surprising that it had health benefits as well.  Will it be as popular in the United States as apple cider vinegar?  Who knows?

Thus, when I stumbled upon this article talking about… duh… Chinese Medicinal uses of  Vinegar, I read it, digested it, and decided to quote some excerpts.

Vinegar (cu) promotes warm energy (yang) and is noted as a disinfectant (it’s anti-bacterial, anti-fungal and anti-viral), a detoxifier, digestive aid and treatment (internal and external) for inflammation.

Thinking about it, I really really doubt if anything can survive the acidity of vinegar.  I thought as a child that my tongue couldn’t =)

About 22 vinegar-making methods are collected in “Qi Min Yao Shu” (“Main Techniques for the Welfare of the People”), a book on agriculture by Jia Sixie in the Northern Wei Dynasty (AD 386-534).

The top four vinegars in China are xiangcu (fragrant vinegar) in Zhenjiang City of Zhejiang Province, lao chencu (mature vinegar) in Shanxi Province, hongqu micu (red yeast vinegar) in Fujian Province and baoning cu (bran vinegar) in Sichuan Province.

That gives me more varieties to try!  But now let’s go to the health benefits:

Chinese people traditionally make vinegar from grains. Sticky rice and rice are widely used in the south while sorghum and millet are more often used in the north.
Bai cu (white vinegar) made from barley is widely used for external application (as on a wound) and in household cleaning.
During hot weather, Chinese would add vinegar to food to improve the appetite and fumigate rooms with vinegar to prevent infectious diseases.
Its uses include relieving diarrhea and jaundice when taken internally, relieving inflammation and stopping bleeding when used in external application.
It is recommended in cases of indigestion from too much greasy food, in cases of internal bleeding and sore throat.
Its many uses were recorded in the “Ben Cao Gang Mu” (“Compendium of Materia Medica”) by famed pharmacist Li Shizhen in the Ming Dynasty (1368-1644).
Modern research confirms the many benefits of vinegar, which is rich in amino acids, vitamins and acetic acid, especially rice vinegars.
It has been found to improve digestion and appetite, and to have anti-fungal, anti-bacterial and anti-viral properties, especially rice and apple cider vinegars.
It is said to be helpful in protecting the liver, expanding blood vessels, working as a diuretic and promoting metabolism of proteins and sugar. Apple cider vinegar is part of many weight-loss programs.
Vinegar can also serve as solvent for certain herbs. By soaking in vinegar, the undesirable side-effect of some herbs like yuan hua (daphne genkwa) and gan sui (euphorbia kansui) can be reduced. Vinegar can also strengthen the effect of herbs like wu wei zi (shizandra berry).

Am not sure about the apple cider vinegar references though – am not very familiar with it, although it DOES work for me as a salad dressing.

Vinegar can expand the functions of other herbs, like danggui (angelica) and baishao (root of herbaceous peony) when they are soaked in vinegar – then they also can help stop bleeding. Vinegar “guides” other herbs toward the liver.
We all know vinegar is sour and bitter, so don’t overdo it, lest it cause stomach upset. Drinking it on an empty stomach produces too much gastric acid.
Adding vinegar to soup made by boiling bones can help release the calcium in the bones.
Applying vinegar to a burn can help lower the temperature and reduce skin damage. Adding a little vinegar to bath water can improve the skin.

If we can market vinegar as a sexual tonic, we’ll be RICH!  Now for the “legend of the sour wine” (my own title)

Du Kang, an emperor of the Xia Dynasty (21-16st century BC) is said to have invented wine making and taught the methods to his son Hei Ta who later moved to Zhenjiang (in today’s Zhejiang Province) with his own followers.
They didn’t want to throw away their wine and kept it in a sealed jar.
When he opened the jar 21 days later, he smelled a delicious fragrance and found the liquid was both sour and sweet.
It was kept as seasoning and named cu (vinegar), which combines the characters for “21 days” and for “wine.”

“21 days” and “wine” eh, I’m sure that will come in handy in trivial pursuit!  Anyway, the author concludes the article with some uses for vinegar.  Bleh, all I know is that the black stuff TASTES good!  Personally, I tell my patients to eat their salads with vinaigrette dressing as the acidity of the dressing counters the raw and coldness of the salad, thus preventing cold diseases in the Spleen and Stomach.  And that’s if they HAVE to eat their veggies raw.  In Chinese Medicine, we prefer everything cooked.  I know, I know what about nutrient preservation, etc – let’s save that for another blog entry.

Not Quite Laughing Gas… Chinese Herbs Produce Nitric Oxide, Benefits Heart

salvia1 184x300 Not Quite Laughing Gas... Chinese Herbs Produce Nitric Oxide, Benefits Heart

Dan Shen

Extry! Extry! Read all about it!

Chinese Herbs prove to help the body produce nitric oxide! (NO)

NO? Wait a minute, isn’t that laughing gas?

An anesthetic?

Not quite.  Laughing gas is NITROUS oxide.  This is nitric oxide.

Anyway, scientists at the University of Texas Health Science Center in Houston will be publishing an article in the paper Free Radical Biology and Medicine entitled “Nitric Oxide Bioactivity of Traditional Chinese Medicines Used for Cardiovascular Indications”

In plain English that means “We’ve studied how traditional heart benefiting herbs produce NO.  Looks like ancient tradition is proved by science yet again, despite attempts of skeptics to hide the fact.”

(Interestingly, when I read the news article on personalliberty.com, I thought it looked familiar… turns out similar news articles have been out since August…)

What’s the big deal about nitric oxide? A quick Wikipedia scan reveals:

NO is an important messenger molecule involved in many physiological and pathological processes within the mammalian body both beneficial and detrimental. Appropriate levels of NO production are important in protecting an organ such as the liver from ischemic damage. However sustained levels of NO production result in direct tissue toxicity and contribute to the vascular collapse associated with septic shock, whereas chronic expression of NO is associated with various carcinomas and inflammatory conditions including juvenile diabetes, multiple sclerosis, arthritis and ulcerative colitis.

Nitric oxide should not be confused with nitrous oxide (N2O), a general anaesthetic and greenhouse gas, or with nitrogen dioxide (NO2), which is another air pollutant. The nitric oxide molecule is a free radical, which is relevant to understanding its high reactivity.

Despite being a simple molecule, NO is a fundamental player in the fields of neuroscience, physiology, and immunology, and was proclaimed “Molecule of the Year” in 1992.

Oooookay, so like any other substance, it’s got it’s good and bad points.  Let’s look at more.  I’ll highlight the good stuff:

NO is one of the few gaseous signaling molecules known. It is a key vertebrate biological messenger, playing a role in a variety of biological processes. Nitric oxide, known as the ‘endothelium-derived relaxing factor‘, or ‘EDRF’, is biosynthesised endogenously from arginine and oxygen by various nitric oxide synthase (NOS) enzymes and by reduction of inorganic nitrate. The endothelium (inner lining) of blood vessels use nitric oxide to signal the surrounding smooth muscle to relax, thus resulting in vasodilation and increasing blood flow. Nitric oxide is highly reactive (having a lifetime of a few seconds), yet diffuses freely across membranes. These attributes make nitric oxide ideal for a transient paracrine (between adjacent cells) and autocrine (within a single cell) signaling molecule. The production of nitric oxide is elevated in populations living at high-altitudes, which helps these people avoid hypoxia by aiding in pulmonary vasculature vasodilation. Effects include vasodilatation, neurotransmission (see Gasotransmitters), modulation of the hair cycle, production of reactive nitrogen intermediates and penile erections (through its ability to vasodilate). Nitroglycerin and amyl nitrite serve as vasodilators because they are converted to nitric oxide in the body. Sildenafil, popularly known by the trade name Viagra, stimulates erections primarily by enhancing signaling through the nitric oxide pathway in the penis.

Whoah, whoah WHOAH! Penile erections? I should emphasize that in the tags! Get me more hits!

Seriously though, I can see how NO helps the heart – by promoting vasodilation and decreasing blood pressure (I presume).  So what happens when we don’t get enough of nitric oxide?

Nitric oxide (NO) contributes to vessel homeostasis by inhibiting vascular smooth muscle contraction and growth, platelet aggregation, and leukocyte adhesion to the endothelium. Humans with atherosclerosis, diabetes, or hypertension often show impaired NO pathways. A high-salt intake was demonstrated to attenuate NO production, although bioavailability remains unregulated.

Again, in plain English, people with heart disease, diabetes and high blood pressure don’t have enough of the stuff.  Of course, one can have TOO MUCH of the stuff too and that’s… bad.  Feel free to browse the entire wiki article.  Oh I love wikipedia.

Back to the personalliberty.com article:  I checked to see the actual abstract of the study and here is an excerpt:

We tested a group of convenience samples of TCMs obtained here in the U.S. for endogenous nitrite, nitrate, nitroso, nitrite reductase activity as well as their ability to relax isolated aortic rings. The results from this study reveal that all of the TCMs tested reveal NO bioactivity through their inherent nitrite and nitrate content and their ability to reduce nitrite to NO. Many of the TCM extracts contain a nitrite reductase activity greater by 1000 times than that of biological tissues. Repletion of biological nitrite and nitrate by these extracts and providing a natural system for NO generation in both endothelium dependent and independent mechanisms may account for some of the therapeutic effects of TCMs.

Wowzers! Scientific proof on how Chinese medicine works! Who would have thought?!!?

And now finally, the article that inspired this blog post, in it’s entirety:

New research has uncovered the scientific basis of ancient Chinese herbal formulas that have been shown to improve cardiovascular health.

Based on their work, researchers at the University of Texas Health Science Center in Houston believe the formulas help prevent heart disease by producing large amounts of nitric oxide, which is known for its artery-widening properties that facilitate blood flow and circulation.

The compound also lowers pressure and reduces the formation of artery-clogging plaque that may cause blood clots, the scientists explain.

Dr. Nathan S. Bryan, the study’s senior author and assistant professor in the university’s Brown Foundation Institute of Molecular Medicine for the Prevention of Human Diseases, explains that “[these herbal formulas] have profound nitric oxide bioactivity primarily through the enhancement of nitric oxide in the inner walls of blood vessels, but also through their ability to convert nitrite and nitrate into nitric oxide.”

Herbal medicines, along with massages and acupuncture, have formed the basis of traditional Chinese medicine for thousands of years, contributing to the treatment of cancer, cardiovascular disease and diabetes.

Nice summary!

Oh and I checked some of the August articles.  They named dan shen and gua lou as some of the herbs they used.  Bought from a Houston store… perhaps with the help of Yao Ming?

I must emphasize once again that one can have too much of a good thing.  Chinese herbs and other medications, whether alternative or conventional, must be prescribed by a qualified practitioner.
