When walking in a landscape that is still green, of course we will feel fresh and not look away because our eyes are spoiled with green nature (forest). However, have we ever thought whether this plant is useful or not? is this plant wild or ornamental? and various questions that arise in our minds. Nature is an open book for anyone who wants to read it.

Learn from nature.! The habit of using plants as traditional medicine or herbs has been going on since ancient times, until now in modern times we still find some people who use traditional medicine in treatment. Yes, for indigenous peoples of course the forest is everything. The forest is mother, the forest is a living pharmacy. All flora and fauna in the forest are believed to have a purpose and function to live side by side with humans. Premna is a genus of flowering plants in the Lamiaceae family that has various species. This genus is widespread in tropical and subtropical regions in Africa, South Asia, northern Australia, and various islands in the Pacific and Indian Oceans. Generally, in Indonesia this one plant is known as Bebuas.

If narrowed down, Bebuas in the local name given by the Knasaimos Indigenous Community in the Tehit language is called Yorban. Premna or Yorban plants are often used for traditional medicine, especially to treat inflammation, immune-related diseases, stomach disorders, external wound healing, and skin diseases. "We (Kitong) here still have a forest that is used as a laboratory for learning for anyone," said Tono Agustinus Woloin (Tono "Bapak" is the name in the Tehit language) opening a conversation with the Bentara Papua Team regarding medicinal plants.

The weather that day was so hot, we decided to chat outside the house with Tono Woloin, that's our nickname for him. While looking for a slightly cooler place, we finally chose to sit on the front porch of the Kna Mandiri Cooperative, in Sira Village, Saifi District, South Sorong Regency. Tono Woloin, a middle-aged man who has a good memory and is rich in local knowledge. We can proudly call it a living asset owned by the Tehit Tribe, especially the Knasasimos Sub-Tribe indigenous community.

In the Sira and Mangroholo village areas, many plants are used as medicine by the local people, such as the Bebuas plant. "We call it Yorban, I don't know what the Indonesian name for yorban is," said Tono Woloin. According to the man from Mlaswat Village, this plant is still used as a medicine to heal boils. If there are boils on a part of the body that have not yet released pus, you can use Yorban leaves. How to use it is also simple, just heat it over a fire and then stick it on the boil. "Once you stick it on like that, the pus will come out quickly," he said. The same method can also be applied to unstable body temperature (fever).

This plant, which reaches a height of around 7-9 meters, not only uses the leaves as medicine but also as a food flavoring. The leaves, which are oval-shaped and have a slightly rounded base, are often used as a flavoring when cooking, the aroma is very strong when crushed or crushed. "In the past, my mother (they) cooked fish soup using this only," said the man from Mlaswat Village. According to Tono Woloin, when cooking something with sauce like fish, you can actually use Yorban leaves without using other spices.

For the Knasaimos Indigenous Community, there are no taboos when consuming this wild plant. Whether young or old, Yorban leaves are very helpful in the midst of a scope that still has minimal access to both facilities and infrastructure. Tono Woloin also expressed his feelings, because knowledge of this traditional medicine is starting to fade among village youth. This is influenced by social gaps such as the influence of digitalization and also communication within the family. Tono said that, "Children don't ask, we and parents don't tell stories so it's cut off at tono tong (us)".

"I am grateful to be able to witness firsthand how parents used to use plants in the forest as medicine. Because from the roots of wood, bark, rope, leaves to soil can take me who lives in the village to Bali," he concluded.
