Ethnobotanical study on Dragon Boat Festival Tea in Songyang County, East China
This ethnobotanical study systematically documents the 144 plant species comprising Songyang Dragon Boat Festival Tea, analyzes their traditional medicinal applications and resource sustainability, and highlights the urgent need for conservation strategies to protect this vital biocultural heritage from intergenerational knowledge loss and over-exploitation.

Imagine the Dragon Boat Festival not just as a time for racing boats and eating sticky rice dumplings, but as a giant, ancient pharmacy where the "medicine" comes in a cup of tea. This research paper is like a detailed inventory list and a field guide for the specific herbal tea brewed in Songyang County, East China, during this festival.
Here is the story of the study, broken down into simple terms:
1. The Mission: Saving a "Living Library"
Think of the local knowledge about these herbal teas as a living library written in people's heads rather than on paper. For over 2,000 years, people in Songyang have been gathering wild plants to brew tea that clears heat, fights off sickness, and keeps the body balanced.
However, this library is in danger. The "librarians" (the older generation) are passing away, and the "books" (the wild plants) are being picked faster than they can grow back. The researchers wanted to rush in, take a snapshot of this library, and write down exactly what plants are used, how they are made, and what they cure before the knowledge disappears forever.
2. The Detective Work: Gathering the Clues
The research team acted like botanical detectives. They visited eight villages and one busy local market in Songyang County just before the festival.
- The Interviewees: They talked to 93 people. Most were older (over 50) and had only a primary school education. This makes sense because, in this culture, the deep knowledge of nature is often passed down through daily life and farming, not through university textbooks.
- The Method: They asked simple questions: "What plant is this?" "Which part do you use?" "How do you make it?" and "What sickness does it fix?" They also collected physical samples of the plants to double-check their names in a lab.
3. The Discovery: A Massive "Plant Buffet"
The results were surprising. The team found that the Songyang Dragon Boat Festival Tea isn't made from just one or two herbs; it's a massive buffet of 144 different plant species.
- The Top Ingredients: Just like a famous soup has a secret blend of spices, this tea has three "star chefs" that appear most often:
- Lophatherum gracile (a type of bamboo grass).
- Lindera aggregata (a type of spice bush).
- Aster turbinatus (a wild aster flower).
- The Family Tree: The plants mostly belong to two big families: the Daisy family (Asteraceae) and the Mint family (Lamiaceae). These are the "popular kids" of the plant world in this region.
- How it's Made: The process is simple but careful. You take the whole plant (or specific parts like twigs), wash off the dirt, dry it in the sun, and chop it up. It's like preparing a garden salad, but for medicine.
4. What Does the Tea Fix?
The researchers categorized the "ailments" the tea treats, similar to how a doctor groups symptoms.
- The Top Two Problems: The tea is most famous for fixing digestive issues (like stomach aches and indigestion) and respiratory issues (like coughs and sore throats).
- The Consensus: When the researchers asked different people about these two problems, almost everyone agreed on the same plants to use. This high level of agreement suggests these remedies are trusted and time-tested.
- Other Uses: The tea is also used for skin problems, muscle pain, and even to help with snake bites or insect stings.
5. The Warning Sign: A Fragile Ecosystem
Here is the most critical part of the story. While the tea is a treasure, the plants themselves are in trouble.
- The Red List: Out of the 144 plants used, 83 of them (more than half!) are on China's "Red List" of threatened species. This means they are rare or at risk of disappearing.
- The Endemic Species: 31 of these plants are "endemic," meaning they are like unique local celebrities that only exist in this specific part of China. If they are picked to death, they are gone forever.
- The Conflict: There is a tug-of-war. The tea is a vital part of the local culture and health, but the way it is currently made relies heavily on picking wild plants. If we keep picking them without replanting, the "library" will run out of books.
6. The Solution: A Balanced Approach
The paper concludes that we need to protect this tradition without destroying the plants.
- Don't Stop the Tea: The tea is a valuable part of the culture and a source of natural health.
- Change the Source: Instead of just running into the wild and picking everything, the researchers suggest we need to farm these plants. We should figure out how to grow them in gardens or farms so we don't have to harvest the rare wild ones.
- Teach the Young: We need to make sure the younger generation learns these recipes before the older generation forgets them.
In a nutshell: This paper is a rescue mission. It documents a rich, 2,000-year-old tradition of herbal tea in Songyang, reveals that it uses a huge variety of plants (many of which are rare), and warns that to keep this tradition alive, we must stop over-harvesting the wild and start growing our own "medicine garden."
