Are you finding it helpful to break the study of Rosemary down into chunks? We have more to go. Today, think of this plant as a spunky, warm, broad-acting antiviral, antibacterial, antifungal, antiparasitic. Here’s a memorable list of actions:
Flea and Tick Repellent
Used in powdered form, alone, or combined with other repellent powders or diatomaceous earth.
Its been tested against the following and found effective: Staphylcoccus aureus , S. albus , Vibrio cholerae , Escherichia coli , and Corynebacteria, Remember that as a rule of thumb, direct antibacterial actions of herbs only apply to putting them in direct contact with the bacteria. So, for example, an external manifestation of staph would respond to topical Rosemary applications. The essential oil is recommended but you could also make a strong wash or compress using an infusion.
Rosemary oil has been found very effective in preventing the spoilage of meat due to gram negative and gram positive bacteria, I suppose this would make rosemary a good choice for marinades.
Candida albicans does not flourish in its presence, nor does Aspergillus parasiticus. Rosemary is one of the herbs used for chronic Candidacis.
Rosemary essential oil is a traditional remedy for scabies.
Dr. Linda White and Steven Foster state that rosemary is a useful remedy for many types of parasites, and washing the infested parts of the body with rosemary tea may stop a scabies infestation.
We get mixed reports here. According to tradition, it works but a clinical trial evaluated it as a failure when it comes to head lice. As usual, finding specifics about what quality and formulation of rosemary was used in the study is missing.
First Aid for Wounds
To prevent infection, application of Rosemary as an essential oil or infusion (wash or compress) is a good choice for first aid. Remember that the essential oil ought to be diluted in a carrier oil. Virgin coconut oil is my first choice because its antimicrobial all by itself. Or, you could dilute it in fresh aloe vera gel…another good antiseptic wound healer. Wounds that are slow to heal benefit from a salve made with the oil or fresh leaf infused lard (never use salves on fresh wounds!)
No one really knows why insect repellents work and good luck finding anything that’s 100% effective. In laboratories repellents are tested against a scale of +100 (repels) to –100 (attracts). DEET, the main ingredient in most popular commercial insect repellents, scores a mere +10 in lab bioassays. Not so great for the “most repellent” of such products (which contain 5-10% DEET). The other bad news for DEET is that its a powerful neurotoxin capable of causing some severe side effects in its users. (see links below)
Here’s some good news, in the same lab tests done on nepetalactone, the essential oil in catnip that gives it it’s characteristic odor, catnip oil scored a whopping +49% to +59% at a high dose. At lower doses it still outscored DEET coming in at +39% to +53%! Catnip oil is ten times stronger than DEET at repelling mosquitoes!
To make your own catnip repellent its best to purchase a high grade catnip essential oil and mix it with coconut oil at a 5% dilution. That means 20 drops of essential oil to 20 ml. carrier oil. You don’t have to apply it to your skin for it to be effective, you can rub it into outdoor clothing (a scarf, headband, gloves, socks,pants leg).
Alternatively, if you can’t get the oil, try making a hydrosol of your own garden catnip and spray it on.
There are other great herbal insect repellents for a wide range of insect pests, here are a few of them:
- Both Mountain Mint (Pycnanthemum muticum) and Pennyroyal (Hedeoma pulegioides) contain the powerful insect repellent, pulegone – Pulegium means “flea” in Latin. Way back in the first century Pliny made note of pennyroyal’s effectiveness against fleas. Beware of using it on your pets though. There are reports of dog deaths due to their exposure wearing pennyroyal laced collars. Mountain mint may be safer and more effective. Just pick some fresh leaves and rub them on your clothing. Pregnant women should avoid both plants since they can induce miscarriage.
- 1) Vinegar infused with lemon balm
- 2) Citronella is widely available,especially popular as candles to burn and ward off the insects. Some are allergic to it.
- 3) Lemon Eucalyptus essential oil is very effective. Just add a few drops to a spray bottle of water.
- 4) Other useful essential oils to use this way are Lemongrass oil, cinnamon, peppermint, clove, rosemary, castor oil. Try a mix of 30 drops lavender oil to two tablespoons of a carrier oil.I like combining oils as much as I can.
- 5) Make your own catnip/rosemary oil: Roll 2 cups of stemmed catnip and 1 cup of cut rosemary sprigs with a rolling pin. Pack them into a sterile jar and cover with a good quality, light body care oil like grapeseed oil or jojoba. Seal and store in a cool dark place for two weeks. Shake it daily. When its finished, strain it, seal and refrigerate for up to 8 months.
Need a fly repellent? Here’s a recipe used in the forest service:
2 cups white vinegar
1 cup Avon Skin-so-Soft
1 cup water
1 T eucalyptus oil (available at drugstore)
20 oz spray bottle
- This one is a fly repellent for horses:
1 oz citronella oil
2 oz Skin-so-Soft or Coat-so-Soft
1 cup cider vinegar
1 cup water
20 oz spray bottle
You can also add a couple of tablespoons of garlic powder (NOT garlic salt) to their feed a month before fly season, or 1/4-1/2 cup apple cider vinegar (depending on size) to feed. The vinegar has been reported to help prevent entroliths in places where horses are prone to them (mostly in the west).
Note that the color of clothing makes a difference, wearing dark colored clothing attracts the bugs. Best to stick with white or khaki. Also, evergreens tend to harbor mosquitoes.
- Ticks – Rose Geranium oil. DEET is used against ticks so it may be that catnip will work on them,too? I’ll have to experiment with that.
- Chiggers: actually this is a technique that works. If you’ve been out in suspected chigger territory, rub your legs frequently with firm pressure. This destroys chiggers before they get a chance to dig in.
Do you have any other natural repellent suggestions? Or examples of what’s worked best for you? Please share….
