Here's more about the plant, from a local wild edibles expert:

Yam A: The Alata - Eat The Weeds and other things, too

The Dioscorea Dilemma: Which ones are edible, and what parts? One wouldn’t think wild yams would be hard to sort out. It only took me about a dozen years. I’m not talking about anything related to the sweet potato. That’s the Ipomoea family. I’m talking about real yams, in the Dioscorea family...

Should you grow white or purple Dioscorea alata yams? | The Survival Gardener

Yesterday I was asked whether white Dioscorea alata yams or purple Dioscorea alata yams…

Shucks! Looks like zones 9-11 only.

Dioscorea alata - Plant Finder

 

Yes, it's not for everyone. Sorry.

 

Just had a sweet potato, they were on sale for 97 cents over holidays. White flesh, baked, then later peeled, sliced, and fried in butter and oil.

 

I now eat carnivore, but I do miss me some sweet taters.

 

For decades, yams have been known as being loaded with many nutrients and healthful components. Unfortunately, many people can only access sweet potatoes instead. I have even seen sweet potatoes labeled as 'yams' in grocery stores. The two plants are easily mistaken.

 

I really like sweet potato fries.. don’t think I have eaten a true yam

 

I am just a backyard gardening nerd. We got into serious food growing before the '08 crisis, and just kept learning from there.

 

I haven't tried growing tried yams, had a decent sweet potato harvest this year though. Orange and Red's, a few white ones. The purple ones didn't thrive in my garden. It's a lot of food for the low amount of effort I put into growing them.

I wouldn't mind trying the true yams.

 

The great things about yams is you can leave them buried as an emergency food supply and harvest when needed. Since my BOL is still not fully built....I'm starting with really long term harvest foods.

Possibly "Dioscorea hispida" aka 'nami, kayos, or korot.' Similar poisonous yams in West Africa: "Dioscorea dumetorum" aka 'Bitter Yam .'
Grok 2 Ai (beta): "In the context of the Philippines, there isn't a direct reference to a "poison yam called kallot" in the provided search results. However, there are mentions of similar situations or yams that could be related:

Dioscorea hispida: Known in the Philippines as "nami," "kayos," or "korot," this yam is notably toxic when fresh due to saponins and calcium oxalate raphides. It requires extensive processing like slicing, soaking in water for days, and cooking to remove toxins. This species was used in a resistance story during WWII where it was given to Japanese soldiers without proper preparation, leading to their incapacitation. This plant is also referred to as an "intoxicating yam" because of its potential to cause intoxication or even death if consumed in large amounts without detoxification. BITTER YAM: Overview, Uses, Side Effects, Precautions, Interactions, Dosing and Reviews
Poisoning Incidents: There have been incidents in the Philippines where improper preparation of yams or similar root crops like cassava led to mass poisonings. For example, in 2005, cassava, which can also be toxic if not prepared correctly, led to deaths and illnesses in an elementary school in Bohol.

While "kallot" isn't explicitly mentioned, "Dioscorea hispida" might be what you're referring to under a different local name or a variant thereof. The need for careful preparation before consumption due to its poisonous nature aligns with the general theme of toxic yams in the Philippines. However, without direct evidence linking "kallot" to any specific yam, this is an inference based on the closest known toxic yam in the region."

I was wondering when someone would mention the prep needed to make them edible.

 

DTG just dropped a long video on true yams:
