In South Asian countries e.g., Bangladesh and India, a plant with a unique leaf structure is found. It seems like three leaves are attached to form a single leaf. This plant is Bengal Arum (Scientific name: Typhonium trilobatum). In my country, Bangladesh Typhonium trilobatum is commonly known as ‘Kharkon’, ‘Ghat kachu’, or ‘Ghatkol’. In Bengali, ‘kachu’ is the common name for all aroids. So, you can understand that Bengal Arum belongs to the family Araceae. This perennial plant has some traditional medicinal uses. So, its toxicity and medicinal values should be explored more by scientists.

- Anti-ulcerogenic use: It is believed that Bengal Arum has anti-ulcerogenic effects.
Toxicity
Typhonium trilobatum contains calcium oxalate crystals in its body. The most concentration of this toxin is found in tubers/corms (/aroid roots).
Bengal Arum toxicity causes-
- Acute pain in the oral cavity
- Breathing difficulties/ discomfort (upper airway compromise, respiratory distress)
- High heart rate
- Higher blood pressure
- Swollen lips
- Swollen tongue
- Saliva drooling/ increased salivation
These signs and symptoms may appear within 10 to 15 minutes of consuming Typhonium trilobatum. So, stay away from consuming this plant by yourself.
Calcium oxalate forms oxalic acid in blood streams and sediments in the liver, heart, lungs, and kidney. So, to save these organs, avoid taking Bengal Arum.
Control
Bengal Arum is hard to control as it has an underground corm (tuber). To effectively control this plant, underground parts have to be removed.
