[What is St. John's wort]

St. John’s wort (Hypericum perforatum) has a history of use as a medicine dating back to ancient Greece, where it was used for a range of illnesses, including various nervous disorders. St. John’s wort also has antibacterial, antioxidant, and antiviral properties. Because of its anti-inflammatory properties, it has been applied to the skin to help heal wounds and burns. St. John’s wort is one of the most commonly purchased herbal products in the United States.

In recent years, St. John’s wort has been studied extensively as a treatment for depression. Most studies show that St. John’s wort may help treat mild-to-moderate depression, and has fewer side effects than most other prescription antidepressants.

https://en.wikipedia.org/wiki/Polymer

A polymer is a large molecule (macromolecule) composed of repeating structural units. These sub-units are typically connected by covalent chemical bonds. Although the term polymer is sometimes taken to refer to plastics, it actually encompasses a large class of compounds comprising both natural and synthetic materials with a wide variety of properties.

Because of the extraordinary range of properties of polymeric materials, they play an essential and ubiquitous role in everyday life. This role ranges from familiar synthetic plastics and elastomers to natural biopolymers such as nucleic acids and proteins that are essential for life.

Natural polymeric materials such as shellac, amber, wool, silk and natural rubber have been used for centuries. A variety of other natural polymers exist, such as cellulose, which is the main constituent of wood and paper. The list of synthetic polymers includes synthetic rubber, Bakelite, neoprene, nylon, PVC, polystyrene, polyethylene, polypropylene, polyacrylonitrile, PVB, silicone, and many more.

Most commonly, the continuously linked backbone of a polymer used for the preparation of plastics consists mainly of carbon atoms. A simple example is polyethylene (‘polythene’ in British English), whose repeating unit is based on ethylene monomer. However, other structures do exist; for example, elements such as silicon form familiar materials such as silicones, examples being Silly Putty and waterproof plumbing sealant. Oxygen is also commonly present in polymer backbones, such as those of polyethylene glycol, polysaccharides (in glycosidic bonds), and DNA (in phosphodiester bonds).

Polymers are studied in the fields of polymer chemistry, polymer physics, and polymer science…

Polymerization is the process of combining many small molecules known as monomers into a covalently bonded chain or network. During the polymerization process, some chemical groups may be lost from each monomer. This is the case, for example, in the polymerization of PET polyester. The monomers are terephthalic acid (HOOC-C6H4-COOH) and ethylene glycol (HO-CH2-CH2-OH) but the repeating unit is -OC-C6H4-COO-CH2-CH2-O-, which corresponds to the combination of the two monomers with the loss of two water molecules. The distinct piece of each monomer that is incorporated into the polymer is known as a repeat unit or monomer residue…

https://en.wikipedia.org/wiki/Synthetic_rubber

Synthetic rubber is any type of artificial elastomer, invariably a polymer. An elastomer is a material with the mechanical (or material) property that it can undergo much more elastic deformation under stress than most materials and still return to its previous size without permanent deformation.About 15 billion kilograms of rubbers are produced annually, and of that amount two thirds is synthetic…

Natural vs synthetic rubber

Natural rubber, coming from latex, is mainly poly-cis-isoprene containing traces of impurities. Although it exhibits many excellent properties, natural rubber is often inferior to synthetic rubbers, especially with respect to its thermal stability and its compatibility with petroleum products.

Synthetic rubber is made by the polymerization of a variety of petroleum-based precursors called monomers. The most prevalent synthetic rubbers are styrene-butadiene rubbers (SBR) derived from the copolymerization of styrene and 1,3-butadiene. Other synthetic rubbers are prepared from isoprene (2-methyl-1,3-butadiene), chloroprene (2-chloro-1,3-butadiene), and isobutylene (methylpropene) with a small percentage of isoprene for cross-linking. These and other monomers can be mixed in various proportions to be copolymerized to produce products with a range of physical, mechanical, and chemical properties. The monomers can be produced pure and the addition of impurities or additives can be controlled by design to give optimal properties. Polymerization of pure monomers can be better controlled to give a desired proportion of cis and trans double bonds…

Pure, Organic Cacao from the Rainforest

Through nutritional analysis, we are learning and naming over 300 chemical compounds at play in cacao. We are exploring their psychochemical effects on us — our central nervous systems, our bodies, minds and moods.

Antioxidant Rich:
Cocoa beans are rich in specific antioxidants such as catechins and epicatechins, the antioxidants found in green tea, as well as flavonoids, proanthocyanidins and polyphenols, the antioxidants found in red wine and grape seeds.

A Healthy Cardiovascular System:
Many studies published in the past few years have revealed the health-promoting properties of cacao, especially on the cardiovascular system. One study concluded that cocoa powder and dark chocolate favorably affect cardiovascular disease risk status by modestly reducing LDL oxidation susceptibility, and increasing serum total antioxidant capacity and HDL-cholesterol concentrations.

Improved Concentration and Mood:
Take pure dark chocolate to increase concentration and elevate mood. Cacao is also a unique source of the biogenic amine phenylethylamine (PEA). PEA is known as the molecule of love. When taken orally, it increases attention and concentration, and elevates mood.

Organic Chocolate Infused with 11 Powerful Rainforest Botanicals

Chocamaca is more than a great-tasting, healthy chocolate. It contains 11 other unique ingredients to provide your body with an enjoyable source of concentrated nutrients from wild, whole foods. These powerful botanicals provide energy, boost your immune system, support a healthy heart and so much more. Here’s what else you’ll find in each delicious ball of Chocamaca:

Kiwicha — promotes good cardiovascular health*
Maca — supports energy*
Muira Puama — supports nervous system*
Suma — supports hormonal balance*
Camu Camu — provides high concentration of natural vitamin C*
Blue-Green Algae — helps boost your immune system*
Catuaba — supports increased libido*
Jatoba — supports endurance and overall strength*
Fucus — helps stimulate lymphatic circulation*
Bitter Orange — an aid to soothing stomach disturbances*
Canela — provides invigoration*

Low in Calories and Fat

Compared to other chocolates and candy, Chocamaca is low in calories and fat. If chocolate has a bad reputation as far as health is concerned, it is strictly because of the refined white sugar commercial chocolate contains. Otherwise, pure cacao is a rich source of antioxidants which support a healthy heart, help reduce harmful cholesterol and boost the immune system. Add 11 nutritious herbs, and you have a deliciously healthy treat!

Amazon Herb Company’s Chocamaca goes a big step further in rejoining chocolate with traditional herbs and grains from its original bioregion, then molding them into small spheres reminiscent of Tibetan herb balls.

What is it about chocolate that would make 50% of women reportedly claim to prefer chocolate to sex?
Yes, most chocolate contains some sugar. But chocolate clearly delivers far more than a brief sugar high. Remove the refined white sugar and we move closer to the bitter herb of its origin.

What is it we love so much in chocolate?
Could it be chocolate’s tryptophan, the essential amino acid that enhances serotonin function, hence diminishing anxiety? Theobromine may be the Aztecs’ agent against mental stupor. Or perhaps chocolate’s key to our hearts is its phenylethylamine (PEA) content. Phenylethylamine, commonly called the “love molecule,” is a natural chemical suspected of causing the euphoria experienced by lovers.

PEA’s presence in wild blue-green algae, another ingredient in Chocamaca, may explain the increased energy, enhanced mental clarity and pervasive upbeat optimism experienced by algae eaters.
