Like regular potatoes, purple potatoes with sprouts are not recommended. When potatoes are sprouted, they produce the toxin lobelia, which is a toxic substance that can irritate the mucous membranes and cause nausea, vomiting, dizziness and other symptoms of toxicity when consumed. If the amount of intake is relatively large, it will also cause paralysis of body organs, and serious cases may also lead to death.

But for the newly sprouted purple potatoes, because its toxin has not begun to spread, but concentrated in the sprouted roots, so as long as the root part of the digging away, the other parts can still be eaten. In addition, the toxin of lobelia has an Achilles' heel in that it cannot tolerate prolonged high temperatures. Therefore sprouted purple potatoes can be used to make stews, etc., and long term cooking at high temperatures can effectively remove the toxicity of lobelia. Adding a little vinegar to the cooking process can cause the lobelin to break down faster and detoxify the potatoes more fully, with better flavor.
