Germ Shield

Protects and Very Soothing 08/07/2026
By Sarah Lyn
Love the Germ Shield oil!! Very soothing and I feel that it protects your nasal lining from germs. I have been using it first thing in morn and before going to bed. I recently also used this formula before traveling on an airplane. I know it works because I did not catch any cold or my nose didnâ€™t get stuffy and dry, which I usually get when I travel on an airplane.

Great in a steam inhaler 10/03/2025
By Teri Anderson
Germ Shield helps open up my sinuses and lungs. I use it in a steam inhaler at the first sign of a cold, or when I've been exposed to someone who is sick.

Prevention better than cure 03/06/2024

The old adage, that an ounce of prevention is better than a pound of cure is true for me with Dr. Foster's Germ Shield. I apply it beneath my nostrils as instructed. It is simply amazing! Great scent and medicinal.

great product but always unavailable 03/18/2023

I love the Germ Shield essential oil. I would swab my nose with it every evening and it kept my sinuses open throughout the night and I didn't wake with the usual stuffiness I struggled with. However, I gave it to my daughter, who also has the same nighttime issue and have not been able to get another bottle for myself. As soon as it's back in stock I will definitely purchase more then one bottle. Great product.
Our responseHi Michelle, so glad it's helped you! I'm so sorry it wasn't available when you wanted it. We had a huge run on this formula during the "worldwide situation" the past couple of years when we were saving lots of lives by combining it with steam and people were ordering it like crazy. We've since re-stocked and we have an abundance of this formula now!

I really like the product -- I have had a low grade sinus issue with some post nasal drip - rocking my head back and tapping a few on the back of my throat and a drop or two on each finger for the nostrils helped -- I got a great response alternating with Eucalyptus. I added ATP recently and felt it activated/accelerated it nicely for me, fwiw, and I got over it very quickly -- love back

By Kathleen Virant
Gave it to my daughter before she was flying, used as directed. I also use it under my mask if I have to go in public.
Our responseWonderful - It's a great way to use this essential oil blend! Sometimes people get Germ Blaster (another Dr. Foster's Essentials product) and Germ Shield confused. For anyone reading, this review is about Germ Shield.

Stay healthy throughout flu season 11/23/2015
By Diane Doban
I am taking this every day as a precaution during flu season. I don't believe in flu shots, and feel it is much better to maintain a strong immune system using herbs and vitamins. These formulas are as pure as you can get! Tonic herbs can be taken every day, and I believe the effect is cumulative.

So many uses! Great First aid! 10/27/2015
By STEPHEN SANCHEZ
Wow, what does this not help with. I have used this for so many things. I put this in my quick remedy case. Runny Noses, Minor cuts and insect bites, I used it on a nasty spider bite and I recovered quite well. I have used it on my face for some skin issues. All I know that I will be buying more! Read up on the uses on the site. There is so much this wonder bottle can be used for. A MUST Buy, and a Must USE! Great Stuff!

Excellent Germ Shield Protection 02/25/2015
By Teresa Bradley
I have been using germ shield for the past 9 yrs and I have to say, I am 100% satisfied with this product. I have had maybe 2-3 days that I've caught a cold in those 9 yrs, but other than that, I have not been sick while faithfully using this product. Thank you so much for increasing the size of the bottle.

Essential oils can be
used in the nose

A must-have item during cold and flu season! Inspired by a long trip to Italy during which Dr. Foster caught a bad cold on the airplane (and no Germ Blaster in sight!).

Using essential oils applied in the nostrils (in the airplane restroom), the congestion drained within 5 minutes, and repeated every 1 to 2 hours afterwards throughout the day, the cold disappeared in 24 hours.

The congestion-relieving properties of eucalyptus are legendary and explains why eucalyptus is such a timeless folk remedy for colds and flus, in addition to the other essential oils in this formula.

Benefits:

Nasal Protectant and Decongesting: Use anytime you have a stuffy nose. Especially good when applied just before boarding an airplane or other public transportation where one will be exposed to large numbers of people (with who knows what kinds of germs lurking on their hands and in their noses!)

Hand teeming with germs!
We all need a natural
Hand Sanitizer

Hand Sanitizer: drip one drop in the palm of hand and rub hands together until the oil disappears.
Natural Deodorant: smell fresh! Kills odor-causing bacteria and feels very cooling in the armpits.
On the Skin: Disinfect cuts and scrapes, or use on a rash to soothe skin and control itching.
Other Uses: Another terrific use reported by our customers: applied in the nostrils to halt migraine discomfort.

Quality & Safety:

Organic & Wildcrafted: We only use organic and wildcrafted essential oils. This essential oil blend consists of 100% pure therapeutic grade essential oil in a base of Organic Jojoba oil - no fillers, extenders or preservatives whatsoever.
Clinically-Proven: This blend has been clinically proven in Cynthia Foster M.D.'s practice for over 25 yrs. It is very rare to find a conventionally trained medical doctor who has been using holistic healing methods for decades. Learn more about Dr. Foster
Safety Note: We have diluted this blend in order to protect you and so that you can use it directly out of the bottle directly onto sensitive mucous membranes. Undiluted "neat" essential oils applied inside the nose without a carrier oil can cause burning sensations - and no one likes that.
Details On Our Strict Product Quality

How to Use:

Nasal Application: Use a drop on a tissue or cotton swab to swab the inside of each nostril to protect nasal membranes while in public places such as public transport and to ease migraine discomfort.
Steam Inhalation: Use around 6 drops in a personal steam inhaler or add to a pan of very hot water, cover your head and the pot with a large towel and inhale deeply for around 15 minutes.
Topical Use: Use a drop or two on small cuts and scrapes or other affected areas as needed. Use 1 drop on palms, rub together whenever hand sanitizer is needed.
Natural deodorant: Apply one drop to armpits as needed.
For children or sensitive adults: it does not have to be used inside the nostrils (you will feel a strong cooling sensation), but can be applied to soles of feet, chest, upper back or on the upper lip just under the nose.
