Valerian Benefits and History

Valerian, also known as Valeriana officinalis, is a perennial plant native to Europe and Asia and has naturalized in North America. Valerian is one of the key ingredients in our natural relaxant Formula 303. It seems that insomnia is not really a new occurrence in our society; Valerian, as found in our Formula 303, has been used as a medicinal herb since the time of ancient Greece and Rome. The therapeutic uses of Valerian were described by Hippocrates. Galen first prescribed the insomnia remedy, Valerian, for insomnia in the second century. By the 16th century, it was being used to treat nervousness, shakiness, headaches, and even heart palpitations. Valerian was used during World War II in England as a natural remedy for stress following air raids.

It has been shown through preliminary clinical research that the sedative and anti-anxiety effects of Valerian occur as a result of direct action on the GABA neurotransmitter in the central nervous system. It is believed that valepotriates and the GABA phytonutrient extracts from the root are responsible for the sedative effects. There are numerous studies and anecdotal reports of the valerian root benefits. You may view references to supporting research here: http://umm.edu/health/medical/altmed/herb/valerian

When people think of Valerian, anxiety remedy often comes to mind. Other uses for Valerian have included: restlessness, sleeping disorders based on nervous conditions, anxiety, helping to control panic attacks naturally, tension headaches, intestinal cramps, muscle spasms, menstrual cramps and overall relaxing of the body. It really is a great natural remedy and is the main ingredient in Formula 303 tablets.

Our specially formulated combination is better than typical Valerian tablets or other valerian herb supplements because it is a powerful combination of ingredients for insomnia, relaxation, tension and muscle spasm.* If you see a valerian root sale, don't be misled, you want Formula 303's powerful combination of ingredients.

Due to safety concerns in women who are pregnant or nursing, we recommend that you should not take valerian without medical advice because the possible risks to the fetus or infant have not been evaluated. Also, we recommend that you do not give Valerian products to children under age 3 years because the possible risks to children of this age have not been evaluated. As always, if you have questions, you should consult your family physician or healthcare provider.

Passiflora Benefits

Passiflora, also known as Passion flower has been helpful in some people to reduce restlessness, anxiety, tension and nervousness. Some researchers even believe that Passionflower may also be a mild aphrodisiac. A recent study that included 36 men and women with generalized anxiety disorder revealed that passionflower was as effective as a leading anti-anxiety medication when taken for one month. Passion flower acts therefore, as an all natural tranquilizer. This is a key finding since medication has numerous side effects and medication has been shown to be habit forming. If you are on anxiety medication, alternative treatment is healthier for you. In another study including 91 people with anxiety symptoms it was shown that a natural herbal product containing passionflower and other herbal sedatives substantially decreased symptoms when compared to a placebo.

Most studies are revealing the benefits of herbal remedies in helping relieve tension, stress, anxiety and insomnia and more studies are probably necessary to confirm once and for all what thousands of people have known for several centuries: Valerian helps relieve tension, anxiety and sleep disorders, especially when combined with Passiflora.*

Video: Formula 303 Testimonial

Joan shares her experience with Formula 303.

"This product amazing. I've been telling all of my friends about it. After an accident 7 years ago, I saw my chiropractor who told me to try it. I used to get it at his office, but it's just so much easier (and cheaper) to get it at earthturns. It gives me the relief i need before I go to bed so I can sleep. Thanks for the free shipping."*

"I bought Formula 303 5 months ago to help my back spasm. I cut trees down for work and I was having trouble bending over all day. I usually take 2 tablets just before work or when I'm doing yard work at home and it works great. I definitely recommend this to all my friends."*

"Formula 303 has worked for me for the past 2 years. I just found your site and now will only buy from you. I can't believe how fast you sent it to me and I didn't even have to pay for shipping. I even use less medication now for sleep."*

"Formula 303 is amazing... I was diagnosed with fibromyalgia which causes pain and really makes me tense. This helps me to relax and have less pain. Thanks!"*

"I have nighttime leg cramps that keep me up all night. Not any more."*

"I got this for spasm, but didn't realize it would help my restless legs and insomnia. Definitely give it a try,"*

"When my chiropractor first told me how well the 303 supplement worked, I didn't believe her. However, as they say, the proof is in the pudding. My neck spasm and headaches are so much less on the days that I use it. I am so happy. Thanks DC labs."*

"I notice a big improvement when i'm at work. I like the fact that it's natural. I don't like taking medication."*

"These are the greatest natural muscle relaxers yet! great price, fast delivery, what else could I ask for?"*

"I had trouble sleeping because of neck spasm after a car accident. After two nights using formula303 I finally slept the whole night."*

this product genuinely delivers relief from back pain, and can help one relax enough to go to sleep. I was in so much pain with my back I couldn't even turn over in bed. Together with adjustments at the chiropractor, and rest, this natural treatment made all the difference in the world. It doesn't make you groggy, it doesn't seem to interact with medication. It provides relief, it is gradual, subtle, but it sure worked for me. It's a product I want always to have on hand for those times my back tells me I've done too much!

TOMORROW posted on 12/6/2017
Formula 303 is a light version of a muscle relaxer without the crazy side effects. I wish it was just a little more powerful. I use it for anxiety, and I found it to be ok.

First, I can't say enough about the management & customer service at EarthTurns.com. I've been a customer for several years. Formula 303 has been a game changer for me. I use it for pain, anxiety, sleeplessness. You name it and this product will not let you down. You may have to adjust the dosage depending on your activity, ex: you're at work & have to give a presentation that is stressing you out, a 1/4 - 1/2 a tab would do a world of good. I split them & keep them in my purse. Try them at home 1st of course to see how they affect you. I think the label dose it 2-3 tabs. Word of warning, they do stink but I ignore it because they work.
The best homeopathic pain for my back ever!
