Chapter I Introduction
A. Background of the Study
Psidium Guajava: commonly known as Guava or Bayabas in Filipino terms. It is widely grown in the Philippines. It is a flowering plant, growing 33 feet tall. Guava is ideal for flavoured drinks, sauces, deserts, salads, pies, cakes, puddings, jellies, and chutneys and the fruit may even be dehydrated and powdered to flavour ice cream. Guavas
are
rich
in dietary
fiber,
vitamins A and C, folic
acid,
and
the dietary
minerals, potassium, copper and manganese. Having a generally broad, low-calorie profile of essential nutrients, a single common guava fruit contains about four times the amount
of
vitamin
C
as
an
orange.
Guavas
contain
both carotenoids and polyphenols like gallocatechin, guaijaverin, leucocyanidin and amri toside–the major classes of antioxidant pigments – giving them relatively high potential antioxidant value among plant foods. Guava leaves are used in folk medicine as
a
remedy
for diarrhea
and,
as
well
as
the
bark,
for
their
supposed antimicrobial properties and as an astringent. Guava leaves or bark are used in traditional treatments against diabetes. In Trinidad, a tea made from young leaves is used for diarrhea, dysentery and fever. (http://en.wikipedia.org/wiki/Guava#Fruit). It is in this light that the researchers would like to explore other possibilities of using guava as soap.
B. Statement of the Study This investigation aims to explore the possibility of creating an effective remedy for acne.
C. Hypothesis of the Study The investigators hypothesize that the extract of the leaves of the plant will effectively relieve muscle pains.
D. Objectives of the Study This investigation aims to: 1. Create and test a proposed remedy to muscle pains
E. Significance of the Study This investigation finds an alternative and inexpensive way of relieving/easing muscle fatigue. This is a great help for those people who don’t have enough money to buy commercial pain relievers.
F. Scope and Delimitation of the Study This investigatory project only uses the stem of the plant. Only the stem extract will be used for experimenting. It is limited only to using simple techniques and crude materials used at home; thus, its shelf-life is limited to two weeks to one month only as these materials could not be sterilized completely. Discovering and identifying the compounds present in Oregano is not also included in this study.
G. Definition of Terms
Guava- Guava is a tropical fruit rich in nutrition Extract- An extract is a substance made by extracting a part of a raw material, often by using a solvent such as ethanol or water. Soap- a substance used with water for washing and cleaning, made of a compound of natural oils or fats with sodium hydroxide. Acne- is a common human skin disease, characterized by areas of skin with scaly red skin, blackheads and whiteheads.
Chapter II Review of Related Literature
Guava fruit today is considered minor in terms of commercial world trade but is widely grown in the tropics, enriching the diet of hundreds of millions of people in the tropics of the world. Guava has spread widely throughout the tropics because it thrives in a variety of soils, propagates easily, and bears fruit relatively quickly.
Guavas not only help improve the texture of the skin, they also help prevent a number of skin problems like acne, boils, and pimples. Guavas are rich in astringents that help in tightening both the muscles and skin in the facial region. Astringent is a chemical compound that tends to shrink or constrict body tissues, usually locally after topical medicinal application. They even help tighten and tone loose skin. Being a rich source of vitamins and minerals, guavas contain powerful detoxifiers and antioxidants that help guard against acne, wrinkles, boils, and others.
Vitamin C is essential for healing of wounds such as acne scars and pimples, the National Institutes of Health says. Consume enough of the vitamin daily, because your body doesn't manufacture or store it. Vitamin A is another essential antioxidant that can help heal acne and pimples, says the National Institutes of Health. Guava consists of these vitamins and suitable for acne remedy.
In our present generation, guava is very common and easy to find. We don`t need to buy expensive supplements and medicine in order for us to avoid acne. We can simply use guava extract as remedy to acne.
Chapter III Methodology
A.
Materials
The following were used in this project 1. 50 milligrams Sodium Hydroxide (NaOH) 2. 5 millilitres Guava leaf extract 3. Containers 4. 1 millilitres Lavender scent 5. Pan 6. Spoon
B.
Procedure: Preparation for the Guava Extract Soap Prepare the things needed for the said experiment. Prepare first the stove to be
used then boil the guava leaves in a pan. After boiling, separate the guava leaves from the extract. Then, place the extract in a clean container. Prepare the Sodium Hydroxide (NaOH). Powder the Sodium Hydroxide for faster results. After powdering, boil a little amount of water in a container. After it boils, mix the NaOH with the hot water. Put three spoonful of guava leaf extract. Pour a spoonful lavender scent. Then, stir the mixture. (Note: make sure that the mixture is viscous). Lastly, wait for 24 hours then see the results.
C. Procedure for Testing the Guava Leaf Extract Soap Three human subjects were used for the entire study. The 1st and 2nd test subjects were given the Experimental Guava Leaf Extract Soap, while the last subject was given the Commercially-Sold Beauty Bars. The 3rd Subject will be the control test, while the first two will be the experimental tests. The test subjects applied the experimental and commercial bars to their faces where acne was seen. They will use the beauty bars twice a day for three days. The test subjects recorded what they felt/observes after they applied the beauty bars.
Chapter IV Results and Discussions
When the Guava Leaf Extract Soap was applied on the 1st subject, she felt that it soothes the skin. She felt that it was some kind of burning feeling at first but it felt better the more she used it. She also saw significant effect on her acne, particularly blackheads, as they disappeared on her nose. The 2nd subject also experienced the same effects of the experimental soap. On the other hand, the 3 rd subject which was the control used the commercially-sold beauty bar. She, as expected, felt and observed the positive effect of the beauty bar.
