Vitamin C by June Thomasson, PA-C
Vitamin C
This vitamin is probably the vitamin most consumed, for the most indications, for the longest time in the US. Starting with Linus Pauling’s ground-breaking research, the American vitamin industry has taken off; it has been said that Americans have the most expensive urine in the world! Unfortunately, there still is incomplete research on the actual benefits of supplementation with vitamin C other than curing scurvy. The vitamin is vital to a number of physiological functions; the nonspecific symptom of fatigue could be the first symptom of deficiency. One study suggested 30% of the population is deficient due to poor eating habits; consumption in the diet is still the best source. The recommended daily allowance for men is 90 mg daily, non-pregnant and non-nursing women is 75 mg daily; users of tobacco should consume an additional 35 mg vitamin C daily. About 90 mg is contained in 1/2 cup raw sweet red pepper, 1 large kiwi fruit, 1 cup orange juice (recently opened, see below), 1 cup strawberries, or 1 ½ c cooked broccoli, green peas or kale.
Vitamin C is very frequently used to prevent or treat the common cold. Since Dr. Pauling’s small study in Swiss school children on a ski holiday, amazingly little further research has been done. A Cochrane review of studies in 2000, (the most recent of those included in my sources) concluded that high doses (1-3 grams daily) might decrease the duration of cold symptoms by one to one and a half days in some patients, although doses over 2 grams are more likely to cause stomach upset and diarrhea. That review found that vitamin C taken to prevent colds doesn’t help.
Other possibly effective uses include to decrease sunburn (orally or topically with vitamin E), to slow progression of atherosclerosis (though this may be true only in specific populations), decrease risk of gout, and to decrease risk of developing mouth cancer (but no other cancer). Taken with iron pills, vitamin C does increase the amount of iron absorbed from supplements.
Studies don’t support use of vitamin C for acute bronchitis, Alzheimer’s disease, diabetes prevention, stroke, or “overall mortality”, ie death from any cause. More and larger studies are needed to clear up conflicting evidence regarding efficacy in hay fever, asthma, infertility, mental stress, cardiovascular disease, and cataracts. Of interest are the results of a study in 2002 testing the amount of vitamin C in various ages and sources of orange juice. The study concluded that frozen orange juice consumed within one week of reconstitution is the strongest and most reliable [orange juice] source of the vitamin; all the juices lost about 2% of usable vitamin C daily once opened. Ready-to-drink orange juice should be purchased 3 to 4 weeks before the expiration date and consumed within one week of opening.
Side effects usually don’t occur until daily doses of supplements exceed 2000 mg (2 grams). This is the dose recommended by the makers of EmergenC, which contains 1 gram in each packet. In some people, this amount can cause abdominal bloating and diarrhea, and increase the risk of kidney stones. Higher doses can trigger nausea and vomiting, heartburn, fatigue, headache and affect sleep.

Ginkgo by June Thomasson, PA-C
GINKGO
Gingko is a Chinese herb which has been used for many applications. As is so common, only a few indications stand up to scientific testing, or have been sufficiently tested. In our college population, improving cognitive function is likely to generate the most interest. There are a number of aspects of cognitive function which can be evaluated; the studies and abstracts in my sources report using different names for these functions, and total number of subjects tested is low. However, in healthy, young to middle-aged people, overall memory improvements are likely in the range of 7%. Speed of working memory seems to be the function exhibiting the most improvement.
Several studies of healthy elderly report no protection to or improvement of memory, though in those with mild to moderate age-related memory or cognitive impairment there may be modest improvement. Studies of patients with dementias, including Alzheimer’s also indicate improvement, though these studies are of questionable quality.
Those with Raynaud’s syndrome and vertigo may experience fewer or less severe attacks, and women afflicted with breast tenderness and mood aspects of premenstrual syndrome may experience relief when taking ginkgo.
Other conditions likely improving with administration of ginkgo include the eye conditions diabetic retinopathy and glaucoma, and peripheral vascular disease.
Ginkgo may not be effective in reducing altitude sickness, SAD (seasonal affective disorder), sexual dysfunction, or tinnitus (ringing in the ear). A large trial showed that 240 mg daily in the elderly over 6 years does not significantly reduce the risk of hospitalization or death due to cardiovascular disease.
Initial studies with insufficient reliable evidence to rate effectiveness have been done on people with anxiety, ADHD, fibromyalgia, schizophrenia, recovery from stroke, and vitiligo (a skin condition).
The various chemical compounds in ginkgo can have significant adverse effects. Raw seeds, crude extracts, and even leaves, can cause strong allergic reactions, seizures and even death, or cause cancer; these sources are not recommended. Extracts of ginkgo leaves affect the ability of the liver to process various herbs and medications. Persons with seizure disorder and those taking medications that can increase the risk of seizure should not take ginkgo. Insulin and diabetic medications, and substances affecting blood clotting are likely to be affected, as are many other medications and herbs; it is best not to combine any substance (including ibuprofen, acetaminophen, and other over-the-counter medications) which is pharmacologically active without checking with your practitioner. Anyone with allergy to poison ivy, poison oak, poison sumac, mango rind, and cashew shell oil is more likely to have an allergic reaction to ginkgo.
Dosages vary, and likely vary depending on the extract. Because ginkgo irritates the gut, start at a maximum of 120 milligrams (mg) of standardized extract daily, divided into two or three doses, except for improvement of cognitive function when a single dose can be used. If no benefit occurs, and once the gut is normal, total daily dose can be tapered up to a total daily dose of 600 mg. Ginkgo leaf extract is often combined with American ginseng; this combination was used in studies of ADHD but should not be used for PMS. Ginkgo with co-enzyme Q10 was studied as treatment for fibromyalgia.
In a local grocery store natural health section, six products are available containing gingko. Three are combinations with multiple herbs, including gotu kola, an herb containing caffeine. One is one of the most frequently evaluated standardized extracts, and two are standardized extracts plus a modest amount of the dried whole leaf. There is some evidence of increased benefit from the whole leaf; presumably the amount added to these preparations is insufficient to cause side effects in most people.

NASAL IRRIGATION FOR SINUS CONGESTION by June Thomasson, PA-C
NASAL IRRIGATION FOR SINUS CONGESTION
Upper respiratory infections (“colds”) and sinus infections are a common affliction in the dry climate of Fairbanks. Often resolving without use of antibiotics, or even any medications, some of the discomfort can be alleviated by moisturizing the mucosa. Nasal saline, or salt water, in a squeeze bottle, is the easiest to use, and can help with clearing thickened discharge from a common cold. In persons with a history of sinus infection, this treatment begun at the onset of cold symptoms can decrease the risk of progression to a full sinus infection, and relieves pressure and congestion. Others find increased relief from a larger quantity of water as applied with a Neti pot or syringe. This physically removes some of the discharge, and relieves congestion and pressure. It also improves the function of the cilia, small hairs lining the sinuses. The cilia aid the clearance of discharge from the sinuses.
Neti pots were recently in the news after two people in Louisiana got amoebic brain infections from using tap water for irrigation. Updated instructions suggest boiling water prior to use in irrigation to avoid this. However, our drinking water in Fairbanks is too cold for survival of the organism at fault in Louisiana, so use of Fairbanks or UAF tap water should be fine. (However, if one is immune compromised, using boiled or distilled water would be safer.)To prevent reinfection of oneself, however, wash your pot, bottle, or syringe in hot soapy water after each use, sterilize or replace every two to three weeks, and don’t share your equipment with anyone else.
Directions and recipes are available on the web ( eg from the American Academy of allergy, Asthma and Immunology), or at the Student Health Center for those who have paid the health center fee.

How Important is my Blood Pressure, by Donna Patrick, ANP
Q: What is Blood Pressure?
A: Blood pressure (BP) is the force created as your heart pumps blood and moves it through your blood vessels. A BP reading measures this as it presses against the inside walls of your arteries. High BP means that your heart is working harder than it should. It’s also a sign that your blood vessels are being damaged. If left untreated, high BP can lead to serious problems such as stroke, blindness, heart attacks, kidney and heart failure. High BP is often referred to as the “Silent Killer” and can even cause death.
Q: What do the numbers mean when I have my BP taken?
A: Two measurements are taken:
- Systolic BP is the top number which measures the force while your heart pumps. A normal healthy systolic BP is below 120.
- Diastolic BP is the bottom number which measures the force between heart beats. A normal healthy diastolic BP is below 80.
Q: But I thought my BP was good if it is below 140/90?
A: With the new guidelines BPs between 120/80 and 139/89 are now considered to be Prehypertension. This new classification is intended to identify those individuals who are able to lower their BP with healthy lifestyle changes hopefully preventing hypertension entirely.
Q: How can I tell if I’m having high blood pressure?
A: Since high BP rarely shows symptoms, the only way to know for sure is to check your BP reading. If you haven’t had it checked within the last year, come to the Center for Health & Counseling and we can check it for you.
Q: How can I bring my blood pressure down?
A: If the following measures prove unsuccessful, your health care provider may recommend antihypertensive medication of which many different types are available.
Initially try to make healthy lifestyle changes:
- Don’t smoke cigarettes or use any tobacco product.
- Lose weight if your’re overweight.
- Exercise regularly.
- Limit how much salt you eat. ( There is a lot of hidden salt in foods such as bread and cheeses)
- Limit how much alcohol you drink.
- Reduce stress with relaxation techniques or biofeedback.
Could it be Food Poisoning? by Donna Patrick, ANP
Say Ah by Donna Patrick, ANP
Food Poisoning
Q: I think I may have gotten food poisoning. How can I know for sure?
A: Food poisoning is usually diagnosed based on the person’s physical symptoms and the history of what led to the symptoms. It is not always possible to figure out the particular food or microorganism which may have caused the illness, especially if symptoms have been mild and resolve within a few days.
The symptoms of food poisoning depend on which nasty microbe you may have ingested. There are several! Symptoms may occur anytime from within minutes of eating the bad food to days and even weeks. The most common symptoms associated with food poisoning are:
Nausea
Vomiting
Abdominal pain
Diarrhea, which may be watery or bloody
Fever
Q: I have a lot of the symptoms. What can I take?
A:
Drink lots of fluids.
Eat small, low fat meals.
Rest.
Over the counter antidiarrheal medications such as Imodium and Pepto Bismol are generally NOT recommended and may actually prolong your illness.
Q: Should I come to the clinic?
A: You should come to the clinic if you have:
Symptoms which are persistent or severe.
An underlying medical condition such as diabetes
Temperature greater than 100.4 F
Severe abdominal pain
Inability to eat or drink
Bloody stool or vomit
Q: Am I contagious?
A: A person is considered infectious for at least as long as the vomiting and diarrhea continues, and sometimes longer, depending on the causative organism. These microorganisms are usually spread by hand to mouth contact. Hand washing and staying out of work and school can help prevent transmission.

Spectacular Aurorae Erupt Over Norway
Over the weekend, the Earth’s magnetic field was struck by a coronal mass ejection (CME). The CME — a vast bubble of solar plasma that had erupted from the sun on Jan. 19 — took longer than expected to travel through interplanetary space, but on Sunday it made contact.
