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.
Treatment of Intestinal Parasites. Papaya enzyme supplements may also help fight intestinal parasites, particularly if they contain extracts from the seeds of this tropical fruit. A 2005 study published in the Journal of Medicinal Food reported that both papaya fruit and seeds have anti-parasitic activity.
