Formula 303 - The Natural Relaxant | Chiropractic | Chiropractor

Formula 303 is a combination of two herbs, Valerian Root and Passiflora, and one mineral, Magnesium. It acts to relieve muscle spasms, tension, and stress.

  • Valerian Root (Valeriana officinalis) - used for centuries to calm upset nerves and for treating mood problems, pain and headache. Today homeopaths and herbalists use Valerian root for its antispasmodic, calmative, tranquilizing, carminative (good for upset stomach and digestion) and pain relieving effects.
  • Passion Flower (Passiflora incarnata) - discovered in 1569 it is primarily used as a sedative or nervine to combat excess nervousness and anxiety, to tranquilize, and to promote sleep; as an anodyne, anti-spasmodic and anti-convulsant to treat dysmenorrhea, muscle cramps, and so forth.
  • Magnesium - is one of the most important essential minerals to promote proper nerve function. It is a key element in the stabilization of nerve cells, without which, the nerves would be in a constant state of excitation (a state known as tetany.)

Valerian has been used as a medicinal herb since at least the time of ancient Greece and Rome. Hippocrates described its properties, and Galen later prescribed it as a remedy for insomnia.  

The name Valerian comes from the Latin word valere, meaning "to be strong or healthy", generally thought to refer to its medicinal use, though many references suggest that it also refers to the strong odor.

In researching the use and effectiveness of Valerian Root, many sources tell us that it has been found to be effective for the relief of muscle spasms and nervousness with a resulting calming effect on the system.

The Merck Index and other sources support the fact that Passiflora is an effective calmative and mild analgesic.

Passiflora seems to reduce perception of pain, and has been used for neuralgia, shingles, and general nerve pain. It is very helpful during the menopause, when falling hormone levels can make women prone to anxiety and depression. it also has antispasmodic properties, it can reduce the muscle spasms and gastric spasms hat often accompany stress.

A Magnesium deficiency may cause irritability of nerves and muscles resulting in muscle spasms, leg cramps, nervousness, and backache.
