Magical Elixir
I call this the Elixir, as it holds preventative powers. My former team of fellow managers and I all kept a bottle of this on our desks, as we worked in restaurants and that’s a big area for contagion. Runny nose? Get at that Elixir. Sore throat? Hit up the Elixir one time!(When I say elixir I am in fact referring to the Wellness Formula).Stay well, friends.

Delicious, powerful immunity and great price from Amazon!
I picked this little bottle up from a popular large healthy grocery store a while back for about $25, when I was a classical singer. I used to take it at the first sign of illness, then began keeping it with me to take during the long cold and harsh winters in the Northeast. I have to say, I really think it works as a general immune support, and I love the medicinal herb taste.Now I work a lot more with the public and it continues to be my favorite immunity tonic. I used to take the Wellness Formula pills, but they were very garlicky, and the scent would come out of my pores and in my mouth. Also, I feel that the pills are super strong, almost too good to use on a daily basis. I save those for when I really feel something coming on.For everyday, I take this with me and take some before getting on a train, during and after work. It is not harsh on my stomach and I have been using it for years!Also, the price here is so amazing… I can’t believe they continue to sell it for so much at the other store!

It really works, and you don’t have to go find all of the ingredients yourself+boil them down. Try it in your favorite juice!
THIS is what I take whenever I feel a cold coming on, sore throat, or lymph nodes a’ risin…at all. Prevention is the best medicine!I usually use 2 droppers about 1″ up into glass of orange juice mixed with water. It’s a tolerable flavor, tastes like someone made an herbal tea reduction, kind of Ricola-y. Which basically *is* what an herbal infusion is. It’s so you don’t have to go out and buy/find the 30or so ingredients yourself, boil them down, and infuse them. I can usually feel a reduction in whatever’s swollen/sore/infect-y within an hour or two. Seriously. That’s how my last cold lasted 5 days…stuipdly I stopped taking it, and 2 days later developed a chest cold. But I digress. It does help me a lot.I found it one day when I was feeling a cold coming on and near a store that prides themselves on selling complete comestibles, so I went in there to buy some Kombucha (before I knew it was on sale at 2 of my local grocery stores, like 2 years ago), and the vitamin aisle assistant at the complete comestibles store recommended this. I don’t buy it there regularly any more – that store wants $18 for 2 oz, Amazon is $10.45-$11 for 4oz.

Works great and tastes gross
It’s really hard to drink, and I recommend either putting it to the back of your throat and swallowing or putting some in a little bit of orange juice and then chasing it with something else. It works! It’s a great immune booster, and I definitely recommend taking it when you start feeling that tickle in the back of your throat. It’s also great for taking before your night begins if you know you’re going to have a late night out.

Great immune support.
Smell is strong and taste is as well. Like a strong peppermint Taste. I sue it for me and my daughter and it works great. Just sucks that the price keeps going up for the small bottle they offer. May have to find it cheaper in a local wellness store

Best thing on the market for fighting off an on …
Best thing on the market for fighting off an on coming cold or virus. I’m a senior citizen and I attend several social functions and line dance classes a week. Southern people are very kissy kissy when being greeted by them. A lot of times after going to a class or function and from all the kissy kissy, I come home with a scratchy throat. So I just take a shot of herbal Resistance liquid under my tongue and let it slowing go down my throat. Sometimes there is a little burning in the back of my throat which is good that I know that In have caught simething. This works about 99.5% of whatever is lingering in my system. By morning, I’m feeling great again! I haven’t had a flu shot since 2002. I haven’t had the flu since. Rarely do I get a cold and if I do it lasts about a few days. Always have a bottle on my nightstand in case if I wake up and feel like I coming down with something, I take a half of eye drop full and it knocks it right out!

Like it a lot
Been ordering it on a regular basis. When I’m around sick people I take it as a precautionary. Works well, but not sure if it works as well as the Wellness formual tablets. I like the liquid better only because the dosage is less than the tablets. All in all, I do know it does help my body fight off illnesses. Doesn’t prevent it all the time (sometimes), but it does help lessen the effects. I will continue to buy.

Lifesaver for immune system
I have tried lots of products over the years to help my crappy immune system and this one is very good.I don’t know how or why this works but it seems to. Probably a good idea to only use it for short periods so you don’t get resistant. I start using it at the beginning of cold season or whenever I feel rundown, and use it for a couple of weeks on, then a few months off. This seems to work well in situations where you get rundown and just can’t get your immunity kick started.This is off-label, but I gave this, along with broccoli, to a dog I had that had cancer. Eventually the cancer won, but the cancer grew slower and the dog lived much longer and happier than the vet or I expected. I figured it was worth a try in the face of a terminal problem and I would use this again in that situation. Great product!
