Safely Infuse Oil, Honey or Vinegar With Herbs for Gifts

herb-infused oils

It’s the gift-giving season and we all look for great gift ideas for those we care about. So it’s important to make sure that the gifts we give them don’t make them sick. Infusing oil, honey, or vinegar with herbs is an inexpensive and fun way to pamper our loved-ones that enjoy cooking, but there are significant risks if it isn’t done properly.

Step 1: Sterilize Containers

Start by choosing glass containers that have no chips or cracks. Then thoroughly wash and then sterilize them by boiling them for at least 10 minutes. And don’t forget to sterilize the lids too. This will eliminate any residual pathogens on them.

Step 2: Choose Quality Ingredients

Use only fresh herbs, fruits and vegetables that have no visible blemishes or bruises. This makes it less likely that they will contain harmful bacteria. And then, be sure to wash them well before using them.

Step 3: Refrigerate or Freeze

Storing the finished product in the fridge or freezer makes it less likely that bacteria will grow in it.

Infusing Oil or Honey

Oil creates an environment where air is not present. This makes it easy for certain types of bacteria to grow, including the potentially deadly botulism toxin. Since produce items like garlic and herbs can harbor C. botulinum, it’s a good idea to destroy any bacteria on those items before adding it to oil. You can do this by soaking the products in a citric acid solution to reduce the pH and destroy bacteria that might be present.

Specifically, the citric acid solution needs to be strong enough to bring the pH level of the garlic, herbs, or other ingredients down to 4.2 or less within 24 hours. This paper outlines how you can do that. (This technique is also how manufacturers process infused oils that you can buy off the shelf.)

The oil or honey should also be heated to at least 180 degrees Fahrenheit before adding the other ingredients. Here are complete instructions for safely doing that. Only store these oils, refrigerated for up to 3 weeks.

Infusing Vinegar

Heat the vinegar to 190 degrees Fahrenheit before adding it to the other ingredients, and be sure to fill the container to within 0.25 inches of the top of the container. If you’d like more details, you can find them here. Once you’ve made them, infused vinegars can be safely kept in a cool, dark place for 2-3 months or refrigerated for 6-8 months.


Here are some recipes for flavored oils and vinegars from BON APPÉTIT and Colorado State University Extension to get you started.

Turmeric: Be Careful Where it Comes From

turmericRecent news reports say that one of the world’s largest producers of turmeric adds a lead-laced compound to it before selling it. This producer on Bangladesh adds lead chromate to the powder.

Turmeric itself is extremely healthful and has many beneficial effects as part of the diet. But people in Bangladesh have been consuming it, along with the lead in the additive and are showing many health issues as a result.

Lead is a neurotoxin, and increases the risk of heart and brain disease in adults and interferes with children’s brain development.

An article at states: “Unlike other metals, there is no safe consumption limit for lead, it’s a neurotoxin in its totality,” says the papers’ senior author Stephen Luby, professor of medicine and the director of research for the Center for Innovation in Global Health. “We cannot console ourselves proposing that if the contamination were down to such and such level, it would have been safe.”

The researchers did not find direct evidence of contaminated turmeric beyond Bangladesh, and they point out that food safety checks by the importing countries have incentivized large-scale Bangladesh spice processors to limit the amount of lead added to turmeric destined for export. However, the researchers caution, “the current system of periodic food safety checks may catch only a fraction of the adulterated turmeric being traded worldwide.”

In fact, since 2011, more than 15 brands of turmeric—distributed to countries including the US—have been recalled due to excessive levels of lead.

Researchers and others worldwide are working to find solutions to the problem, but in the meantime, check labels to find out the origin of the turmeric you buy. Whenever possible, buying the turmeric root and shredding it yourself is the safest bet.

Broccoli Sprout Extract May Improve Autism Symptoms

We have all been told that we should eat more broccoli, but now there may be an important reason for people with autism to eat broccoli sprouts. A new research study shows that a chemical found in broccoli sprouts helps improve the symptoms of autism.

The study involved 40 teenage boys and young men, ages 13 to 27. Those who took the chemical, called sulforaphane, showed improvements in social and verbal skills compared to people who took a placebo. Researchers also saw a decrease in repetitive, ritualistic behaviors.

“We believe that this may be preliminary evidence for the first treatment for autism that improves symptoms by apparently correcting some of the underlying cellular problems,” says Paul Talalay, professor of pharmacology and molecular sciences at Johns Hopkins University, who has researched compounds like sulforaphane for 25 years.

“We are far from being able to declare a victory over autism, but this gives us important insights into what might help,” says co-investigator Andrew Zimmerman, professor of pediatric neurology at University of Massachusetts Memorial Medical Center.

Most of those who responded to sulforaphane showed significant improvements within four weeks and continued to improve during the rest of the treatment.

It would be very difficult to achieve the levels of sulforaphane used in the study by eating large amounts of broccoli or other cruciferous vegetables, Talalay notes. The test subjects took sulforaphane-rich broccoli sprout extract administered in capsules.

I encourage everyone to go read the entire studies cited below to find out more about the research so far.

Horse Chestnut: Possible Treatment for Lymphedema

Red Horse ChestnutA few years ago, I was contacted by someone taking part in clinical trials for the use of horse chestnut to treat their lymphedema. I did not update my mother’s research with that information then because this site only publishes information that can be substantiated with research studies or other publications. I’m very careful not to publish any information without being relatively certain of its accuracy. People’s health is involved. That’s no trivial thing.

But last evening I met someone that I hope will become a new friend. During our conversation, she shared that she deals with the very cruel and painful condition known as lymphedema. All of a sudden, those email exchanges with that person about the clinical trials popped into my head. I knew I needed to go do more research to see what the trials had shown.

I found results from several research studies of the effectiveness of horse chestnut for treating Lymphedema. Study results showed that its use reduced leg or arm circumference and helped reduce swelling overall. They also proved that the use of the horse chestnut seed extract removes the toxic components of the herb, making it much safer for use.

Horse chestnut extract can be purchased as supplements, powder and topical cream.

Be sure to go to the Horse Chestnut page of this site for its description and a complete discussion of its medicinal uses.

CBD Oil: Considerations if You Plan to Try it for Chronic Pain

As a chronic pain sufferer myself, the recent hype about CBD as a treatment for pain, anxiety and insomnia have gotten my attention.

CBD short for cannabidiol, is derived from cannabis or marijuana. The interesting thing about CBD is that it contains no THC (tetrahydrocannabinol), which is the component that is psychoactive. So use of CBD promises to be a valuable aid in medicinal therepaies without getting you “high”.

While investigating the effectiveness of its use for these symptoms, I came across some recommendations from the University of Michigan:

  • Don’t smoke or vape. Bottom line is smoking anything harms the lungs. Vaping has been associated with a recent epidemic of lung disease, according to the Centers for Disease Control & Prevention.
  • Purchase from reputable sources. Like vitamins and other supplements, CBD products aren’t regulated or FDA approved to treat disease, so buyer beware. Look for products that have been tested by an independent third party lab “so you don’t end up with a product that has THC in it or a product contaminated with heavy metals or pesticides,” says Boehnke.
  • Route of administration matters. CBD is best taken in pill or capsule form for slow extended release or as an oral tincture (infused oil that contains CBD) for faster effect onset.
  • Start low, go slow. Take a small amount and slowly increase your dosage until you start to get symptom relief over a matter of weeks. Track your symptoms to get a sense of whether or not CBD is a helpful part of your treatment plan.
  • Check your state laws. While medical marijuana is legal in many states, it’s still illegal at the Federal level, putting CBD in a legal gray zone in many areas.

There still isn’t a lot of scientific evidence of the effectiveness of CBD, mostly because of politics. But with more and more states legalizing medicinal marijuana, it’s a sure bet that more study will be done. I will report on it here as I find it.

In the following podcast, Pharmacist Shawna Kraft discusses medical marijuana for cancer patients. She gives an understanding what it is, how to use it and how best to request it.

Herbs That are More Effective in Treating Lyme Than Antibiotics

Garlic bulbsLyme disease is in the news a lot lately. It’s a malady that causes a myriad of terrible symptoms, is carried by infected ticks and a bite can infect a person. The effects are devastating and in some cases, this condition resists standard antibiotic treatments. In these people, the pain, neurological problems and other symptoms can persist for months or even years.

The essential oil of a plant is the result of pressing out an oil containing the fragrance of the plant, hence the term “essential” oil. This essential oil of several medicinal plants has recently been studied by scientists for its ability to fight the Lyme disease bacterium. The herbs studied were myrhh trees, garlic cloves, cinnamon bark, amyris wood, spiked ginger lily blossoms, may chang fruit, oregano, clove buds, citronella, thyme leaves, cumin seeds and allspice berries.

According to a recent Futurity article: “We found that these essential oils were even better at killing the ‘persister’ forms of Lyme bacteria than standard Lyme antibiotics,” says Ying Zhang, professor of molecular microbiology and immunology at Johns Hopkins University’s Bloomberg School of Public Health.

The statistics are amazing. Lyme disease infects approximately 300,000 people in the US each year. It is usally treated with antibiotics and clears up as expected. However, for some unknown reason, there are an unlucky 10-20% of those cases that don’t get better with the antibiotic treatment. Those are referred to as “persistent Lyme infection” or “post-treatment Lyme disease syndrome” and can continue for months or years.

Research studies have found that the use of these herbal essential oils killed the Lyme bacteria and no new bacteria grew back in 21 days. Even the most persistent of bacteria were no match for these potent oils. These results are superior to the antibiotic treatment results.

The studies were done in lab dishes, and there needs to be more testing before the scientists are ready to say that they are to be used by doctors, but this is great news for Lyme sufferers. New treatments could be on the way for the medical community as well as for traditional healers to use with Lyme patients.

Be sure to check out the full descriptions of these plants for the complete information about their beneficial uses.

Pumpkins: Did You Know They are a Berry?

In recent months I have become an avid podcast listener. One of my very favorite podcasts is Ologies by Alie Ward. She interviews, in the most entertaining way, various experts in subjects that generally have “-ology” at the end of the name.

This month, she has been covering various subjects that can relate to autumn and Halloween. In this podcast, Alie interviews pumpkin expert Anne Copeland about her study of pumpkins (Cucurbitology):

Ms. Copeland has published a book about pumpkins called Pumpkin, Pumpkin:: Folklore, History, Planting Hints and Good Eating where she tells all kinds of little-known facts about pumpkins, including recipes.

One of the fun facts she shares with us is the fact that pumpkins are not vegetabes at all. Believe it or not, pumpkins are berries and also a squash.

I recommend listening to the podcast interview with Ms. Copeland, then check out the Pumpkin page of this site to learn about the many medicinal uses for pumpkins.
