Indonesia is a country with fertile soil and rich in plant species. Currently in society the use of medicinal plants as herbal treatment has increased. Elderly people often experience Rheumatoid Arthritis, which is inflammation of the synovial lining of the joints. One of the plants used by the community is red betel leaf (Piper crocatum). However, scientific information related to the potential of red betel as an anti-inflammatory in Rheumatoid Arthritis is still not widely known by the public. This study was conducted to explore the potential of P. crocatum leaves to treat Rheumatoid Arthritis which can be used as references regarding Rheumatoid Arthritis therapy. This study uses a narrative review method from previous studies that were collected related to the topic which was then discussed systematically. By using keywords in the search for Piper crocatum, anti-inflammatory activity, red betel bioactivity, secondary compounds in red betel leaf, and Rheumatoid Arthritis. P. crocatum leaves contain various bioactive compounds. Flavonoids have activity as primary and secondary antioxidants. Flavonoid compounds such as brazilien, brazilin, taxifolin, procyanidin found in red betel have anti-inflammatory activity in rheumatoid arthritis. Brazilin is one of the flavonoid compounds from P. crocatum leaves that has the potential as an anti-inflammatory in rheumatoid arthritis by regulating the transcription factor nuclear factor kappa B (NF-kB) for TNF- expression against inflammation.

During this pandemic, people tend to consume herbal drinks to maintain endurance. One of the plants that people often use as a herbal drink is the lakum plant (cayratia folia). Lakum plants have various antioxidant and immunomodulatory activities. The main content of the lakum plant is flavonoids. The solvents most commonly used as solvents for lakum plant extracts are ethanol, water and methanol. In this study, primary data collection was carried out online, both in the form of national journals and international journals. The results obtained from several journals and other sources could determine the immunomodulatory potential of vacuum plants. In this study, it was found that many of the benefits of these plants include anti-cancer, anti-inflammatory and others, of which a high level of antioxidant activity has an important role in each of the benefits of these plants.

Chronic inflammation is common in infectious diseases, rheumatoid arthritis, gout, and autoimmune diseases. However, using non-steroidal anti-inflammatory drugs (NSAIDs) is accompanied by dangerous side effects. Therefore, searching for safer alternative therapies without side effects is very important. A natural blend of ingredients produced by stingless bees from plants was potential as a remedy. Meanwhile, the potential of kelulut bee products from East Kalimantan as an anti-inflammatory is still unknown. This study aimed to compare the chemical composition of kelulut bee (Trigona apicalis) products and evaluate the anti-inflammatory effect of honey, propolis, and their combination. Propolis extract and honey were determined as secondary metabolites. An anti-inflammatory in vivo assay triggered the edema using carrageenan on male mice and measured its anti-inflammatory power value. Propolis extract and honey from T. apicalis have a promising anti-inflammatory effect and are significantly higher than the positive control. Meanwhile, combining propolis extract and honey did not enhance the anti-inflammatory effect. In addition, combining honey and propolis preparations with a ratio of 75 : 25 has a better effect on reducing edema volume than the other two combinations. Still, it is not better than the treatment with propolis extract or honey alone. The content of polyphenol compounds found in honey and propolis preparations is thought to have an important role in reducing edema volume.
