Introduction to Creeping Fig
Ficus pumila, often called creeping fig or climbing fig, is a fast-growing, evergreen vine. Its ability to adhere to surfaces with aerial rootlets makes it a common choice for covering walls and trellises. It is native to East Asia but is grown in many other regions for its aesthetic appeal. However, questions about its edibility are crucial due to its potential toxicity.
The plant is often confused with the common edible fig (Ficus carica). It is essential to differentiate between the two, as their properties and uses differ substantially. While the common fig yields a sweet, edible fruit, the creeping fig poses significant health risks if consumed.
The Toxic Components
The primary concern with creeping fig is its sap. The sap contains furanocoumarins, which can cause phytophotodermatitis. This reaction occurs when the skin is exposed to the sap and then to sunlight. Symptoms include redness, blistering, and burning sensations. This reaction can be quite severe, especially in individuals with sensitive skin.
Aiyu Jelly: An Exception?
While the raw creeping fig plant should not be eaten, a specific variety of creeping fig (Ficus pumila var. awkeotsang) is used to make aiyu jelly. This Taiwanese dessert is made from the seeds of the fruit, not the fruit itself.
Preparation Method
The preparation process is unique. The seeds are extracted from the fruit and kneaded in water. This process releases a pectin that causes the water to gel, forming the jelly. This method transforms a potentially irritating part of the plant into a culinary delight. The jelly is often served with honey, lemon, and ice.
Table: Creeping Fig vs. Common Fig
| Feature | Creeping Fig (Ficus pumila) | Common Fig (Ficus carica) |
|---|---|---|
| Edibility | Not edible; contains irritants. | Edible; sweet fruit. |
| Fruit | Small, green fruit, not for direct consumption. | Larger fruit, many varieties, edible when ripe. |
| Sap | Contains furanocoumarins; causes skin irritation. | Sap may cause mild irritation in some. |
| Uses | Ornamental vine, aiyu jelly (specific variety). | Fresh fruit, dried fruit, jams. |
| Growth | Fast-growing vine. | Tree or shrub. |
Safety Guidelines When Handling Creeping Fig
To ensure safety when interacting with creeping fig, follow these guidelines:
- Wear Protective Gear: Always wear gloves, long sleeves, and eye protection when pruning or handling the plant.
- Wash Thoroughly: Wash any skin that comes into contact with the sap immediately with soap and water. Avoid sun exposure on affected areas.
- Avoid Ingestion: Do not ingest any part of the creeping fig plant.
- Educate Others: Make sure children and pets are kept away from the plant, and inform others about the risks.
Conclusion
Is creeping fig edible? Generally, the answer is no. The common variety contains a toxic sap that can cause skin irritation and internal distress. A specific variety is used to make aiyu jelly through a special preparation process involving the seeds. For those who encounter this plant, caution is necessary, and protective gear is recommended when handling it. Always be certain of the plant's identity and properties before use to avoid potential health risks.
