Bawang is my helpful plant. Bawang is known as "garlic", it mainly reduces cholesterol in the blood and helps control blood pressure. Bawang or Garlic with scientific name Allium Sativum, is a low herb, which only grows up to sixty centimeters high. Its leaves are flat and linear, with bulbs . This herb is one of the most widely used herbal medicines s and can also be found commonly in the kitchen of households as it is used to spice up food preparations. Its medicinal properties have been known for a long time and have been especially proven during World War II when it was used to treat wounds and infections of soldiers. Garlic’s antibacterial known as allicin, saved many lives of the soldiers as this property prevented the wounds from being infected and developing into gangrene at a later stage by extracting the juice of bawang or garlic and applying to the wounds. Bawang, sometimes spelled as bauang or in English, garlic is known as nature's antibiotic. Its juices inhibit the growth of fungi and viruses thus, prevent viral, yeast, and infections. The preliminary test conducted on this medicinal herb showed some positive results in the treatment of AIDS. Several clinical tests that followed and published studies have shown the efficacy of garlic in lowering cholesterol in the blood and is beneficial to the circulatory system of the body. Today, as more research is done on garlic, more medicinal and therapeutic properties become more evident. As of the present time, lowering of the blood pressure, reduction of platelet aggregation, and the boosting of fibrinolytic activities are among the list of herbal functions of garlic, which is supported by medical findings. Although more clinical studies are needed to support the contention stronger, marked improvements in benign breast diseases have been traced to make progress because of the regular intake of supplements, of which the primary ingredient is garlic. Although controlled trials in terms of anti-cancer activities of garlic have been performed in medical research, it has been proven through population-based studies that substances contain in garlic help in reducing the risk of some types of cancer. Some helpful benefits are Good for the heart, Helps lower bad cholesterol levels (LDL), Aids in lowering blood pressure, Boosts immune system to fight infection, Cough and cold remedy, and relives sore throat.

The bad plant that I have chosen is poison sumac. It is part of the phylum anthrophyta. Its genus and species name is Toxicodendron vernix. This plant is very bad. It only takes 1 nanogram of oil from this plant to cause a rash, and the average human get 100 nanograms of oil every time they come in contact with the plant. The only place where this plant can be found is in wetland areas and areas with flooded soil. Some facts are that it is really woody and it actually grows into a tree instead of a small plant or shrub like poison ivy and poison oak. The poison sumac tree can actually grow to be 30 feet tall. According to some people, poison sumac is the most dangerous plant in the United States. Poison sumac causes huge boils filled with the oil and pus that can spread easily if you break them open. If you try to get rid of the plant and burn it, the oil can then be inhaled and it will caused bleeding in your lungs and you will die immediately. All parts of the plant are poisonous, including the bark.
The good plant that I chose is a sugar maple tree. It is also part of the phylum anthrophyta. It has a genus and species name of Acer saccharum. By far, this is definitely a good plant seeing as how we get most of our syrup and other things from it. It is located in northeastern North America, Georgia, and Texas. It is part of the deciduous tree family. When it seeds, it has a double samara which is two of the helicopter things combined at the seed. One of the most shade tolerant trees in the world. Shade tolerant is when it can just grow out of a little bit of sunlight. The tree can grow in any type of soil except for sand, unless the sand is moist and it has dirt mixed with it. The sugar maple is part of something called hydraulic lift. Hydraulic lift is when the plants roots pull water from way down below and pull it up and disperse it closer to the top of the soil for other plants to use and grow. Acid rain and soil acidification kill the sugar maple more than anything else. The Norway maple is taking over because it is a more urban tree because the salt that is spread out in the winter also hurt the tree a lot. The wood that we get from it are used to make the following: bowling alley lanes, NBA basketball courts, baseball bats, musical instruments such as violins, and pool cues.
