This stuff is good!
I use this product interchangeably along with their wellness formula in capsule form. The drops are more herbal, the capsules are more vitamins.Both products have echinacea in them, which stimulate the immune system for three hours. I will take one product and three hours take the other and go back-and-forth at first signs of an illness. It almost always knocks it out or lightens the severity. I very rarely get sick because of these products!

The Wellness Herbal Resistance Liquid formula -it worked for me…
Bought this 8 oz. bottle recently because a little two ouncer got used up. I’ve not always been the most optimistic about ointments and liquids like this, but gradually its dawned on me that this stuff works for me. Most recently, and most dramatically, I had taken a daily dose (until the 2 oz. bottle was emptied) and had shut down a cold sore blister on the inside of my lip. When I ran out of the Herbal Resistance Liquid, the blister came back. So I ordered the 8 oz. bottle (alcohol-free fromula). Resumed my treatment from the new bottle, and now the blister’s gone. I’d say that’s a fair test. Certainly encouraging to me to use it some more….Update- March 6, 2019 I’m about to order another 8 oz. bottle of the Source Naturals Wellness Herbal Resistance Liquid (alcohol free formula) because I’m down to about the last ounce on my 8 oz. bottle. I’ve upped my overall rating to five (5) stars. because of this formula’s performance for me. Health is very personal- can’t speak for all, but I am highly satisfied and impressed by this stuff! Coincidence- maybe…. But I’ve started reacting to onsets of cold/flu symptoms by downing a dose or three of the liquid with apparent positive results. I used to think herbal meds were mostly wishful thinking, but experience is telling me otherwise.I also use the Wellness Formula Herbal Defense Complex capsules. They seem also to be effective, just less dramatic results. Looking at ONE dose/serving size: Liquid, 1/2 teaspoon; and Capules, 6 capsules. I still use both, but I like the Liquid better, and I have actually become tolerant of the strange flavor of the herbal combination in an unflavored half glass of water. Here’s hoping others will try and like this stuff. Like my wife- finally convinced her to try the liquid, and now she’s a believer too. Got rid of her cold unexpectedly…. Happy wife, happy life.

Builds up immune systems
This really works well! One of my kids likes the taste. The others aren’t crazy about taking it, but it’s definitely not a bad taste! Really helps with immune system.

HOLY GRAIL
BETTER THAN ANY PHARMACIST CAN GIVE FORCOLD AND FLU

Works like Gang Busters, provided you take it in time. Helps otherwise, but taken early, you can avoid the bug completely.
This is the most amazing product. The KEY to it is to take it at the very first sneeze, or cough, or sensation of being under the weather. I take four droppers full as long as I feel sensation. If I didn’t get to it in time, and i has progressed, i take that dose as often as every two hours, or whenever i feel a symptom. The best is if you know you have been around sick people take a couple of doses right, a few hours apart. And you wont even get run down. This is a great product.

Doesn’t taste great, but thats how I know its working!
Give this to the whole family any time a hint of sickness shows. Taste is not ideal but it is a good tool in our arsenal to prevent sickness.

Yin chao in a glycerite format: rockin’!!!
I love this stuff! I find it helpful to turn away a cold that is starting to brew in my throat/sinuses; which I attribute to the yin chao. I like that it is a glycerite, not an alcohol preparation: I feel it is less harsh in my mouth that way, and I also feel that my kids tolerate it better without the burn of alcohol. I like that it is a tincture rather than a pill— I imagine that it goes straight to work without having to dissolve first, although I have no proof of that….It would be great to have the support of this product when traveling, but my actual experience with bringing it along is: has to go in checked baggage because of TSA; but the dropper bottle leaks every time. So after trying various fixes for that, I either double baggie it and try not to feel bad about the wasted product that the reduced pressure in the baggage compartment causes to leak out; or, if it is summer time, just leave it at home or try to buy some in my destination city.
