I love eating singkamas. A singkamas that has been aged for about a week or two. It has a property similar to yacon, blunt taste at harvest time, sweet taste after over ten days.
Its expected shelf life is one to two months under ambient temperature and dry storage condition. Go and age that singkamas before munching.
Singkamas or yam bean is rich in vitamins and minerals and almost no carbohydrates – good for dieting. Known to prevent heart diseases. Rich in dietary fiber, low sodium content and a rich source of potassium.
Other plant parts are poisonous however. Matured seed is poisonous, the rest of the plant except the edible taproot is toxic. It contains retenone, a poison found in other plants like barbasco, tuba plant, jewel vine and duboisia. It is classified by World Health Organization, WHO, as mildly hazardous. Less likely to cause poisoning cause the irritating property makes one vomit. The lethal dose when ingested intentionally is 143 mg per kg body weight.
Yam bean seed poisoning is somewhat similar to cyanide intoxication showing signs such as periodical numbness, nausea, vomiting, difficulty in breathing, loss of consciousness and death if not given attention immediately.
Yam bean seed is a popular insecticide. According to oisat.org – 500 grams seeds are ground and soaked in 20 liters water for one to two days. Applied on plants in early morning or late afternoon. It’s effective against aphids, flea beetles, stink bugs and leaf eating caterpillar. Also been used for killing animal parasites,reducing fish population and poison fishing – pagtutuba ng ilog .
