INTRODUCTION

The itchy leaf is one of the endemic plants of Papua used empirically as a medicine for relieving aches and fatigue. Itchy leaf [ Laportea decumana (Roxb.) Wedd] is one of the plants belonging to the Urticaceae family that sprea d throughout the world to Indonesia (Perdana et al., 2016; Mom et al., 2016). Itchy leaves have long been used by the people of Maluku, Papua, and Papua New Guinea to trea t various health complaints such as pain, stiffness, headache, abdominal pain, muscle, and bruising (Sima rema re et al., 2020; WHO, 2009).

The usage of itchy leaves in society is applied by rubbing the leaves directly on the pa rt body for example stiff, hurt, and painful. To eliminate dizziness in the head, itchy leaves can be used by placing the leaf on the forehead and then can be removed when it felt lighter and better (Rudiyanto, 2015).

Urticaceae family plants generally contain onoridine, tryptophan, histidine, alkaloids, flavonoids, formic acid, and anthraquinone. Moreover in trichomes, these leaves have formic acid and other substances. If the trichomes got into the skin, formic acid was released and affected the widening of the body's pores. Widening these pores stimulates blood circulation to be smoothly relieved the pain, fatigue, and soreness (Sedarnawati & Puro, 2012).

So far, itchy leaves have been developing as ointment and patches (Sima rema re et al., 2015; Simaremare et al., 2018). In the pharmaceutical field, there are several dosage forms used to treat pain in the skin such as powder, cream, gel, or ointment. The researcher is finding the suitable preparation for dermal application pharmacy technology like loose powder. The powder is a cosmetic preparation in the form of a soft, homogeneous fine powder, so it is easily spread or evenly spread on the skin (Rahim et al., 2017). Because the use of itchy leaves is applied topically, the leaves are good to be developed as an anti- oil preparation in the form of powder. So, this study focus to formulate and test the irritation of itchy leaf powder.


METHODOLOGY

Collecting simplicia

The collection of plant samples was obtained from the Manokwariarea, West Papua. Itchy leaves were collected then dried in an oven with a temperature of 40-50 ° C. After completely drying, it was blended to 100 mesh and the refined simplicia was stored in a tightly sealed plastic container.

Powder Formulation


Itchy leaf simplicia and ta lc were weighed according to the formula determined by the analytical scales, then measured the fragrance volume with a measuring cup according to the formula specified. The three ingredients were mixed until homogeneous and put in a sealed container.


Physical quality testing of loose powder

  1. Organoleptic examination

    This test included observations of the form, smell, and color of thirty volunteers. The responses were recorded on each organoleptic test characteristic.

  2. Sticky power examination

Powder weighing 100 mg wa s applied to the surface of the skin with an area of 100 cm2. The location of the skin where the powder wa s applied wa s blown with a rubber blower. The powder that felt from the surface of the skin was collected in parchment paper then weighed (Voight, 1994 ). The percentage of fa lling powder wa s calculated with the equation:

Total as 5 grams of the powder was weighed accurately, inserted into the porcelain exchange with a diameter of 2-4 cm, then dried in an oven at 105°C until the weight will be constant. The percentage moisture of the powder was calculated by the equation:

% Massa = AB X 100% a=A/B X 100%

A = weight of lost powder ma ss B = weight of powder

before dried (Akelesh et al.,2010)

pH Test

The powder was weighed 10 g and put in a 150 ml beaker glass. Amount 90 ml of water 90 ml wa s heated to a temperature of 27 0 C then cooled and added to the beaker. This mixture was mixed until a good suspension is formed and then determined pH within 5 minutes using a pH meter (Akelesh et al., 2010).


Skin Irritation Test

The irrita tion test was carried out using the human 4-hour patch test method in a closed banned. The covering material consisted of round filter paper with a diameter of 2.5 cm and plaster. The test material was placed on the upper right arm of 30 volunteers for 4 hours. The skin was observed at 0, 24, 48, and 72 hours. Assessment of the degree of irrita tion was evaluated by assigning a score from 0 to 4 depending on the severity of visible erythema and edema reactions on the skin. Without erythema: 0, very little erythema (diameter <25mm): 1, clear erythema (25,1-30mm): 2, moderate erythema (30,1-35mm): 3, severe erythema (dark red forming eskar, diameter> 35mm): 4. Without edema: 0, very little edema (almost invisible): 1, clear border edema (thickness<1mm): 2, moderate edema (rising edge ± 1mm): 3, severe edema (edge rising> 1mm and extends): 4. During the a ssessment, the volunteers were allowed to wash the skin of the application site with water, without soap, detergent, and cosmetic products (Pansang et al., 2010).

The organoleptic result was shown in Table 2. In this study samples of itchy leaf, plants were obtained from Manokwari, Papua. Processing has consisted of sampling part of the leaf, then cleaning it first and drying it using direct sunlight and using the oven at 40-50 ° C then blending to be powder simplicia.

The simplicia that has been made to be powder was tested for its physical quality i.e. organoleptic, adhesive power, powder moisture, pH. This physical quality displayed in Tabel 3 was important because it can affect the quality, safety, and consumer interest in a product.

Organoleptic testing of talcum powder is one of the steps in determining the quality of a talc preparation produced. This examination includes color, odor, texture, and shape that are visually observed.

Adhesiveness reflected how strong the bond was between the powder and human skin. This study used the skin of the forearm and the skin of the inner upper arm. Good adhesion of powder will make powder was easy to apply loose powder and the powder will not be quickly removed due to external factors such as friction (Wilkinson & Moore, 1997). The moisture of the preparation is one of the parameters to determine the physical quality of loose powder (Connor, 1986). The pH value is a value that indicated the degree of acidity of a material (Nurhadi, 2012). According to Wasitaatmadja (2007), a very high or very low pH value can increase the absorption power of the skin, thereby allowing the skin to become irritated (Sameng, 2013). The sticky, moisturizing, and pH were shown in Tabel 3.

Skin Irritation Test

An irritation test was carried out to determine safety or allergies caused by skin contact with itchy leaf powder. Skin irritation is caused by several factors that play a role such as the condition of the skin surface, the length of time the material is in contact with the skin, and the concentration of the material (Irsan et al., 2013). Talc irritation test was performed on 30 volunteers aged 18-27 years who had normal skin and were tested on the skin of the inner upper arm for 4 hours and then observed at 0, 24, 48, 72 hours (Table 4).

DISCUSSION

The organoleptic test results showed that the color produced was different between FI, FII, FIII. This was influenced by the number of different itchy leaves for each formula/ Itchy leaf powder has a dark green color and talc has a white color. The more dust it has the greener color of the preparation. The powder on FI, FII, and FIII has the aroma of roses. In the preparation of itchy leaf powder FI, FII has a soft texture, while FIII has a rather rough texture. This is related to the texture of rough itchy leaves and soft talc so the more the amount of itchy leaf powder is used, the more rough the preparation powder will be.

The average fall in powder in the formulation I was the highest and in formulation III was the lowest. This could have been caused by the amount of talc and itchy leaf powder in each formula. In the study conducted by Rahim (2017), the results of adhesion to powder were 67, 61 % to 72.30% and were said to be good with greater stickiness and a lower percentage of powder that fell. With this comparison, FI, FII, FIII preparations of itchy leaf powder can be said to have good adhesion with the percentage of stickiness, respectively: 99.03%, 99.00%, 98.47%.

The results of the average moisture percentage of FI, FII, FIII are 1, 21 %, 1.35%, 1.42%, respectively. These results indicate that the humidity of itchy leaf powder has good moisture following the moisture requirements of the powder according to Akelesh (2010), which is no more than 2%. In Table 4.4 it can be seen that the pH values of itchy leaf powder on FI, FII, and FIII are 5, 98; 6.09; 6.26. According to Wasitaatmadja (1997), the surface of the skin has a certain acidity (pH) that ranges from 4.5 to 6.5, so it can be said that the pH value of itchy leaf powder on FI, FII, and FIII is good and by the pH of human skin.

The irritation test was carried out on 30 volunteers with replication 3 times in each formulation. Positive skin irritation reactions are characterized by a reaction of redness (erythema) and edema in the treated skin area (Irsa n et al., 2013). The irritation test results showed that all volunteers gave a zero value (0) for erythema, ie no / no erythema, and zero value (0) for edema ie no / without edema at 0 hours, 24 hours, 48 hours, and 72 hours. So, the formula for itchy powder does not irritate the skin and is safe to use as a topical preparation.


CONCLUSION

Based on the research conducted, it can be concluded that itchy leaf powder has FI adhesive power (99, 03%), FII (99.0%), FIII (98.47%). FI humidity (1, 21 %), FII (1.35%), FIII (1.42%). pH FI (5.98), FII (6.10), FIII(6.22), itchy leaf powder has good physical quality. It can also be concluded that itchy leaf powder does not irritate human skin characterized by the absence of edema and erythema in 30 volunteers.
