INTRODUCTION
Inflammation is an essential immune response as a strategy to protect tissue damage caused by microbes, injury and other harmful conditions 1. In general, inflammation is classified into acute inflammation and chronic inflammation. Acute inflammation is a very useful process in helping to immobilize the injured area and allowing the immune system to heal the wound. On the other hand, chronic inflammation becomes a problem for wounds. Inflamed tissue stimulates immune cells from the bloodstream to amplify the inflammatory response 2.
Anti-inflammatory drugs such as Nonsteroidal Anti-Inflammatory Drugs (NSAIDs) are the most successful drugs used in the world by a large number of patients 3. However, NSAIDs can cause various side effects including gastrointestinal (GI), cardiovascular (CV) disturbances, high blood pressure, kidney toxicity, worsening of congestive heart failure, and hepatotoxicity 4–7.
Plants have played an important role in maintaining human health and improving the quality of human life for hundreds of years and serve as highly valuable medicines 8,9. Natural medicines have been increasingly used in recent years as alternative treatments for inflammation due to their relatively mild side effects 10,11 Previous studies have found that various plants have different pharmacological activities, including anti-inflammatory activity 12–14. One of the plants known to have many benefits, including Binahong or which has the Latin name of Anredera cordifolia (Ten) 15.
Classification of A. cordifolia (Ten) plant is as follows: Kingdom: Plantae. Subkingdom: Tracheobionta, Division: Spermatophyta, Subdivision: Angiospermae, Class: Magnoliopsida, Order: Caryophyllales, Family: Basellaceaegenus: Anredera and Species: Anredera cordifolia (Ten) 16.
A. cordifolia (Ten) has been shown to have activities such as antidiabetic 17, antibacterial 18–20, anti hematoma 21, antihyperlipidemic 22, antioxidant 23, analgesic 24,25, and treatment of kidney failure 26.
However, there is no complete literature regarding its phytochemical content and its use as an anti-inflammatory. Therefore, it is important to develop knowledge related to drugs that are sourced from natural ingredients that are useful in drug discovery efforts in the future. This review aims to provide up-to-date information and obtain a comprehensive review of the anti-inflammatory activity of A. cordifolia (Ten).

Kurniawan et.al, tested the anti-inflammatory activity of binahong leaves extract by dividing the male rats into five groups, each group was given a different dose as follows: group 1 (5ml aquadest), group 2 (mefenamic acid 12.6mg/200g BW), group 3 (A. cordifolia (Ten) extract 25.2mg/200g BW), group 4 (A. cordifolia (Ten) extract 50.4mg/200g BW) , group 5 ( A. cordifolia (Ten) extract 100.8mg/200g BW). The leaf extract of A. cordifolia (Ten) has anti-inflammatory properties as indicated by a decrease in the volume of hind paw edema of rats. The anti-inflammatory properties of each dose were 25.2 mg/200 g BW, 50.4 mg/200 g BW, and 100.8 mg/200 g BW respectively by 5.17%, 10.12%, and 1.92% 32. In line with previous studies using the method of induction of carrageenan on rat paws, the research of Yuziani et al. examined the anti-inflammatory effect of the ethanolic extract of the leaves of A. cordifolia (Ten) (EEDB) orally was carried out on 5 treatment groups, group 1 was given 1% CMC suspension (SCMC), group 2 was DSS (diclofenac sodium suspension) at a dose of 2.25 mg/kg BW as for comparison, groups 3, 4, and 5 were given EEDB doses of 100 mg/kg BW, 200 mg/kg BW, and 400 mg/kg BW. The ethanol extract of binahong leaves showed effectiveness against anti-inflammatory by decreasing the volume of hind paw edema 34.
Another study by Sutrisno et.al, reported that the leaf extract of A. cordifolia (Ten) showed the ability to inhibit hemolysis of red blood cells in a hypotonic solution. The optimum concentration for the leaf extract of A. cordifolia (Ten) is 100ppm with 81% inhibition of hemolysis. The increase in this concentration resulted in a decrease in the ability of the extract to stabilize the red blood cell membrane from hemolysis. The results of this study prove that the leaf extract of A. cordifolia (Ten) has anti-inflammatory activity 33.
Laksmitawati et.al, proved that the anti-inflammatory potential of A. cordifolia (Ten) leaf extract in a pure macrophage cell line was induced by lipopolysaccharide (RAW 264.7). Cell viability test was carried out by MTS test. Parameters that have been measured to determine anti-inflammatory activity are interleukin-1β (IL-1β), tumor necrosis factor (TNF)-α, nitric oxide (NO and IL-6). A. cordifolia (Ten) plants with a concentration of 50g/ml can significantly reduce levels of TNF- (250.3 pg/ml), IL-1β (50 g/ml), IL-6 (10 g/ml), and NO (50 g/ml). This study proves that A. cordifolia (Ten) has anti-inflammatory potential by inhibiting inflammatory mediator activity, including TNF-, IL-1β, IL-6, and NO 35.
In another study, the anti-inflammatory activity was also tested by Susanti, G. by conducting experiments on the number of (Polymorphonuclear) PMN neutrophils in male sprague dawley rats, which were divided into 5 experimental groups, each group was given an extract of A. cordifolia (Ten) with different levels, where in group 1 was given ointment base, group 2 was given povidone iodine ointment, group 3 was given ointment extract (10%), group 4 was given ointment (20%), and group 5 was given ointment extract (40%). Ointment is reported after 4 hours of incision. In testing the effectiveness between groups with independent t-test, it has shown a significant difference (p<0.05) except in the positive control group and 40% extract, Post Hoc test showed that there was a difference in effectiveness between the administration of leaf extract ointment of A. cordifolia (Ten) and povidone iodine ointment. From this test, it was concluded that the leaf ointment of A. cordifolia (Ten) at 40% level has an anti-inflammatory effect with a decrease in neutrophil PMN by 81.25% in incision but lower than povidone iodine ointment which decreases the number of neutrophil PMN by 84.64% 36.
CONCLUSIONS
The A. cordifolia (Ten) plant has an important role in society for medicine, including inflammation. The A. cordifolia (Ten) plant also contains phytochemicals that we can use in everyday life. This review describes the importance of A. cordifolia (Ten) as an anti-inflammatory agent and has a variety of chemical. Several pharmacological studies reported the potential of A. cordifolia (Ten) for the treatment of diseases associated with inflammatory stimuli. This study also confirmed the anti-inflammatory effect in vitro and in vivo, A. cordifolia (Ten) showed anti-inflammatory activity by several mechanisms including by decreasing the volume of paw edema, inhibition of hemolysis, inhibition of inflammatory mediators TNF-, IL-1β, IL-6, and NO. , and a decrease in the number of PMN neutrophils.
The chemical content of A. cordifolia (Ten) has high value and benefits because it has natural phytochemical compounds that have potential, especially in plant parts, namely the leaves. Phytochemical components that have been found include essential oils, saponins, phenolics, triterpenoids, steroids, flavonoids, tannins and alkaloids.
However, further research needs to be done to understand the metabolic processes and the role of metabolites as anti-inflammatory in the body as a prelude to the development of new anti-inflammatory drugs in the future.
