By locating red, green and blue LEDs adjacent to one another, and properly mixing the amount of their output (Zhao et al. 2002), the resulting light is white in appearance. 1  Figure 4. Spectral power distributions of several types of LEDs. 2  Figure 5.

Home Remedy for Upset Stomach #3 â Papaya. Papaya fruit or papaya enzyme capsules are both effective at assisting with digestion. Papaya contains the enzymes papain and chymopapain, which are similar to digestive enzymes. Papain is used in many commercial meat tenderizers because it helps break down proteins.
Inside the inner cavity of the fruit are black, round seeds encased in a gelatinous-like substance. Papaya's seeds are edible, although their peppery flavor is somewhat bitter. The fruit, as well as the other parts of the papaya tree, contain papain, an enzyme that helps digest proteins. This enzyme is especially concentrated in the fruit when it is unripe. Papain is extracted to make digestive enzyme dietary supplements and is also used as an ingredient in some chewing gums.
