Finger nails can reflect some nutrient levels though. If a person's nail bed (skin under exposed nail) is spoon shaped (depressed in the middle like a spoon) or pale rather than pink, it can reflect low iron in the blood (hemoglobin). Nails can develop side to side ridges (bows ridges) because of fever, inflammation in the body or a short term illness (acute). Fine longitudinal ridges from cuticle to nail tip tend to develop with age and are not significant. Protein malnutrition will effect nail growth and health since it is the building material that comprise nails. Biotin deficiency can be seen in nails (also as reddened skin) though it is extremely rare. There is no Recommended Dietary Allowances for biotin as it is present in many foods throughout the food chain. Other than that, once damaged, a nail takes approximately 9 months to grow from the cuticle (growing end) to the tip of a person's finger where it can be trimmed off. Other nail changes like white lines in the nail occur because of damage to the nail base when pushing back the cuticle or an abnormal hardening (keratinization) of the nail during formation.

Beautiful Nails features silica and calcium, and contains a variety of nutrients which will provide you with specific nutritional support for strong, healthy nails. Silica (silicon) is a trace mineral used by the skeletal system to add strength to the bones. It has a similar strengthening effect on the nails. Calcium is also included since a deficiency can lead to brittle or soft, splitting nails, as well as vertical ridges on the nail. No sugar, salt, starch, yeast, artificial coloring, flavoring, or preservatives added. Components in this product are derived from natural sources. Natural protective coating utilized.

This two part system includes Nail Strengthening Creme and Liquid Nail Hardener: The Creme nourishes dry, damaged, cracked nails and cuticles, and promotes growth. Nail Strengthening Creme contains a special protein and vitamin complex which was originally designed for the hooves of champion horses, making them stronger and more resilient to breaking and chipping. Due to its efficacy, it soon became a popular item in upscale department stores. This absorptive Creme is formulated to be massaged over the nails (it can actually be used over nail polish) and cuticles. The Hardener interacts (cross-links) with the nail protein fibers to help promote longer, stronger, harder and more durable nails. Although the Hardener may be applied over nail polish, it is important that a base coat is used, which comes into direct contact with the nail.

Here is what thins blood, so you would avoid those things:

Foods that Naturally Thin the Blood 

There are a number of foods and supplements that are known to thin the blood. These include foods with high amounts of aspirin like substances called salicylates, omega-3 fatty acids, foods with natural antibiotic properties and vitamin E supplements.

It is important to note that while many Americans have problems with blood clots, it is not true that blood thinning foods are desirable for everyone in the population. I have been an easy bleeder all of my life, so I have compiled much of the information on this list so I know which foods to limit in order to keep my blood from being too thin. People taking prescription anticoagulant drugs also need to be careful not to consume too many foods with natural blood thinning compounds in addition to their regular medication. One of my relatives is on a prescription anticoagulant drug for blood clots and has gotten eye hemorrhages from ingesting too many blood thinning foods in conjunction with his prescription medication.

Interestingly, my relative was given a list of foods high in vitamin K so he would know what foods to limit so as not to reduce the effectiveness of his medication. However he was not given a list of foods that have their own anticoagulant properties, which is taken in conjunction with his medication could cause bleeding problems. He found some information on his own about blood thinning foods after he had a couple of eye hemorrhages.

Blood coagulation should fall within a desirable range. If blood coagulates too easily, clots can form which in turn can lead to adverse health conditions such as heart attacks. However, if blood doesn't clot enough, conditions such as hematuria (blood in the urine), hemorrhages, heavy periods in women, nosebleeds and bleeding strokes may occur. If a person's blood isn't clotting enough and he has surgery or a traumatic event like a car accident, he could have a serious problem by losing too much blood if any wounds or surgical incisions failed to clot properly.

Some of the foods that are generally thought to have natural blood thinning compounds are listed below. Please note that this is a hodge podge list based on information I've collected over the years based on my own experiences and my assortment of alternative health books, so it's possible it may contain some errors. See your doctor before you implement any diet, supplement or exercise changes, especially if you are taking any prescription medications or have any health concerns related to coagulation.

Salicylates

One type of natural blood thinners are substances that block vitamin K. These include salicylates. The most well known of these is aspirin, but many foods, such as preservatives and flavorings, also contain salicylates or aspirin like substances. Some individuals are known to be aspirin or salicylate sensitive. I'm one of those salicylate sensitive types, but I have found that I can eat more salicylates as long as I eat a balanced amount of vitamin K foods, too. (Vitamin K plays an important role in the body's in blood clotting processes.)

Foods that are generally high in salicylates include many spices, most fruit, especially dried fruits, nuts, and also some flavorings and preservatives.

Herbs and spices high in salicylates include:

• Curry powder
• Cayenne pepper
• Ginger
• Paprika
• Thyme
• Cinnamon
• Dill
• Oregano
• Turmeric
• Licorice
• Peppermint

In Ayurvedic (traditional Indian medicine) many of the above spices are known as "warming spices". I think this is because by thinning the blood they increase a person's blood circulation, which in turn speeds up the metabolism and makes a person feel warmer.

My family was really cold one late evening at Disneyland, but as soon as we ate some churros we all warmed up. We did not know why at the time, but later realized it was because the churros were dipped in sugar with cinnamon, a spice high in blood thinning compounds and known as a warming spice in Ayurvedic medicine.

One of my children has had trouble with night sweats, so we put him on a diet that among other changes limited the amount of salicylates he consumed. That seemed to help him stay much cooler at night.

Fruits high in salicylates include

• Raisins
• Prunes
• Cherries
• Cranberries
• Blueberries
• Grapes
• Strawberries
• Tangerines
• Oranges

Other substance high in salicylates:

• Almonds
• Chewing gum
• Honey
• Peppermints
• Vinegar
• Wine
• Almonds
• Vinegar
• Cider
  

Though there are some exceptions, in general most meat, fish, dairy, grains and vegetable foods are not high in salicylates. Many types of fish do however have blood thinning properties due to their omega-3 fatty acid content, as noted below.

Vitamin E

Vitamin E is an antagonist to vitamin K. Some foods and topical substances these days are preserved with vitamin E, so it pays to read labels carefully. One of my sons, who also seems to be an easy bleeder like me, developed severe nose bleeds from a hand lotion that had vitamin E used as a preservative.

Foods high in vitamin E may not necessarily thin the blood, as many foods high in vitamin E, such as spinach and broccoli also contain significant amounts of vitamin K, which tend to clot the blood.

I was prescribed vitamin E supplements at one time by a doctor for fibrocystic breasts. Afterwards, I developed an increased number of bleeding and bruising problems. Then I did some research on my own and realized vitamin E could thin the blood. Most medical articles states that people have to take relatively large doses of vitamin E in order for it to have an effect on coagulation. However, I don't think that is true for everyone. For people like me who are easy bleeders even small amounts of vitamin E can cause bleeding issues.

Vitamin B6?

This is just an anecdotal report based on my own experience, but I took a vitamin B6 supplement at one time and developed a really bad nose bleed shortly afterwards. The nose bleed stopped when I had a vitamin K rich salad, so I do think that the bleeding was from a lack of vitamin K and not other causes, such as trauma or high blood pressure. The vitamin B6 tablet was the only change I made in my usual diet and routine that day.

Interestingly, one of my health books noted that vitamin B6 lowers estrogen levels, and it is well established through medical studies that increased estrogen levels are linked to blood clots. As such, if vitamin B6 does lower estrogen levels, then it may make sense that it may also thin the blood. However, I have never found any studies noting this association, so at this time the link between vitamin B6 and thinner blood is just a hypothesis in my part based on information from my health books, my own experience and logical deduction.

Omega- 3 Fatty Acids

Omega-3 fatty acids have received a lot of press lately because of their ability to lower cholesterol levels and make the blood less prone to clotting. Fish oil is usually high in omega-3s and can be ingested either through purchasing capsules or by eating fatty fish. Fish with high amounts of omega-3s include:

• Mackerel
• Anchovies
• Salmon
• Albacore tuna
• Mackerel
• Lake Trout
• Herring

When eating fish, one danger is that many fish have high mercury levels, so experts often have mixed recommendations on exactly just how healthy eating a lot of seafood is for most people.

The chart in this link to the U.S. Environmental Protection Agency web site contains a table of mercury levels in commercial fish and shellfish. Fish may be a great food for people who are at risk for blood clots, but for easy bleeders like me it is a food I need to limit, regardless of mercury levels.

Additional Selected Foods With Compounds That Thin the Blood

• Tree Ear
• Jicama
• Garlic
• Onions
• Olive Oil

Garlic and onions are natural antibiotics that can kill the intestinal bacteria that manufacture vitamin K. Many studies have found that long term prescription antibiotic use can cause bleeding problems due to a vitamin K deficiency. However, for people like me who seem to always be short on vitamin K, even small amounts of foods with natural antibiotics properties, like garlic and onions, are problematic. I often avoid eating at Italian restaurants because of their liberal use of garlic. When I do eat Italian food, I also try to have have a salad with lots of leafy green vegetables high in vitamin K as a part of my meal.

James A. Duke, author of several books on herbal medicine, notes that garlic has nine different compounds that are antiaggregants (compounds that prevent the blood platelets from sticking together).

Exercise

Based on studies of female athletes, vigorous exercise seems to lower vitamin K levels. Women who are elite athletes, i.e. those who over exercise, instead of being healthy actually are at risk for hypoestrogenism, osteoporosis and vitamin K deficiency. Vitamin K is necessary to clot the blood, so by logical deduction then it may be prudent to consider the possibility that over exercising may thin the blood since it is known to lower levels of vitamin K.

At the other end of the spectrum, we know that people who remain stationary for long periods, such as people on bed rest, in car trips or travelers on long plane flights, are at risk for blood clots. One of my relatives developed a blood clot in his leg on a flight from Europe to the U.S. and had to have emergency surgery shortly after landing in the U.S.

By logical deduction then, the table below may illustrate the links between the conditions associated with remaining stationary and the conditions with over exercising, two conditions at the opposite end of the spectrum.

Sunshine / Vitamin D?

In Ayurvedic medicine, sunshine is supposed to be good for a person's circulation, which I've found usually means it also thins the blood. As noted above, other Ayurvedic remedies for improving circulation, such as cinnamon and ginger, have actually been proven in modern medical studies to be natural blood thinners. As such, it would be logical to consider the possibility that if Ayurvedic medicine was correct about the spices thinning the blood, they may have been right about sunshine, too.

Interestingly, a recent medical study found that a "clinical trial of a biologically active metabolite of Vitamin D3 demonstrated an unanticipated reduction of thrombosis in cancer patients." Vitamin D is a fat soluble vitamin that we can obtain in two ways: 1) through food; or 2) it can be synthesized by the body after exposure to sunshine.

I don't know if these means that sunshine would have the same impact on blood as the vitamin D from the study, but it is interesting food for thought. If sunshine is found to be a blood thinner, it would confirm what Ayurvedic practitioners have thought to be true for thousands of years.

Summary

It is well known that foods that elevate vitamin K levels, such as lettuce and broccoli, may clot the blood. People who are taking anticoagulants are often warned to limit these types of foods so they don't counteract the effectiveness of their medicine.

However, it is often overlooked that many foods and environmental factors, especially those that lower vitamin K levels, may thin the blood. This information may be important for people on anticoagulants to be aware of in order to prevent their blood from becoming too thin.

Some people, like me, have genetic disorders that make us easy bleeders. However I have found that by controlling my diet by monitoring how much of the foods listed above I consume, I can usually keep my bleeding problems under control.

i have had that happen.  those drugs can cause severe muscle cramps.  it should say that on the side effects.  it happens to me ever so often if i have to take them.  it depends on the kind, some do it, some don't (to me). i would have the dr switch to a different kind of pain killer or at least a different brand.

you would have to take quite a bit to kill your liver, so don't freak out, it just happens sometimes.  keep hydrated (drink lots of water).
