[How to get it]

First, we collect raw propolis from beehives, then extract by low temperature with ethanol. Filter and concentrate, we get the pure propolis block at 90% to 95%.

[Introduction]

Propolis comes from the substance like natural resin, which is collected by the bees from exudates of plants branches and bud the chemical substances of Propolis are found to be various, such as beeswax, resin, incense lipids, aromatic oil, fat-soluble oils, pollen and other organic matter. Studies have shown that the source of propolis resin in material has three types: bees collected plants secreted fluid, secretion in vivo metabolism of bee, and involvement in the process of forming the material.

We can supply Propolis Extract with food-grade and medicine-grade .The raw materiall is came from non-polluting food grade propolis .Propolis extract was made of high-grade propolis. It maintains the propolis effective ingredients during the procedure of extraction under constant low temperature , taking off the useless substances and sterilization.

[Function]

Propolis is a natural product processed by bees mixed with glutinous and its secretion.

Propolis contains more than 20 kinds of useful flavonoids, rich vitamins, enzymes, amino acids and other microelements, etc. Propolis is called “purple gold” owing to its valued nutrients.

Propolis can remove free radical, lower blood sugar and blood fat, soften blood vessels, improve micro-circulation, enhance immunity, anti-bacteria and anti-cancer.

Chameleons don’t change color to match their environment; it’s just the opposite. How do they do it? By manipulating tiny crystals in their skin. Now, UC Berkeley researchers are on a quest to create synthetic chameleon skin inspired by these reptiles’ uncanny ability.

— How do Chameleons Change Color?

Chameleons are some of the most brilliantly colored animals on the planet. But how did they evolve the ability to change color?

Scientists used to believe that chameleons changed color by spreading out pigments in their skin, much like octopuses or squid do.

The top layer of chameleon skin – called the epidermis – contains yellow pigment cells called xanthophores, and red pigment cells called erythrophores. But the amount of pigment in the cells stays the same, even when the chameleon changes color.

Just beneath the chameleon’s skin is a layer of cells called iridophores. These cells contain microscopic salt crystals, which are arranged in a three-dimensional pattern like oranges stacked on a fruit stand.

When light hits the crystals, some wavelengths are absorbed and some are reflected. The result, to our eyes, is the beautiful rainbow of colors on the chameleon’s skin. But what we’re actually seeing is light that is bouncing off of these tiny crystals. What we perceive as green, for example, is blue wavelengths of light being reflected off the crystals and through the layer of yellow xanthophore cells in the chameleon’s epidermis. The result is bright green skin that contains no green pigment!

The process of changing color is called metachrosis.

— Why do Chameleons Change Color?

Chameleons don’t change color to match their environment. In fact, it’s just the opposite.

Their baseline is camouflage.

When chameleons are relaxed, they’re mostly green. They naturally blend into their home in the forest canopy. They even mimic leaves by dancing around a little.

But when they feel threatened, annoyed, or just want to show a little swagger, that’s when their color changes.

Scientists once thought that chameleons color-changing abilities allowed them to better camouflage themselves. Most species of chameleons live high in the forest canopy and their various shades of green provide natural camouflage. Even their movement provides camouflage – they dance around to mimic leaves blowing in the wind.

In fact, chameleons change color primarily to communicate with each other, as though they were living mood rings. Males will warn each other about their territory and females will change color to let males know whether they’re interested in breeding.

Chameleons also have a second layer of iridiophore cells just beneath the first. The crystals in that layer are larger and reflect light waves in the infrared wavelengths. This suggests that chameleons are also changing colors to regulate their temperature, according to Milinkovitch. Chameleons are cold-blooded and heat their bodies with the warmth of the sun.
