Toona sinensis doesn't have too many food taboos, but there are some points for attention. The details are as follows:

First, you should recognize Toona sinensis correctly, otherwise you won't eat it.

First of all, let's talk about several kinds of buds that look more like Toona sinensis: Qishu bud, Holly tender bud, Melia azedarach tender bud and Toona sinensis bud. When they are still buds, few people can distinguish them from their buds, especially after they are all taken captive from trees, and basically no one knows them by looking at them. If you eat these kinds by mistake, of course, you will suffer. Please see the following figure for details:

(1 is Qimiao, 2 is Holly, 3 is Toona sinensis and 4 is Melia azedarach)

Figure 1 is Qimiao bud, which is the most similar to Toona sinensis bud, but it may cause some people to be allergic, and the symptoms of allergy are a lot of red spots. You kill me with seven knives? , said is the toxicity of pure tree, people in it, light skin itching, if the entrance, attack in the throat, and may cause suffocation.

among the four comparisons, the second one is the tender seedling of Ilex. Generally speaking, it has no harm, but it tastes a little bad, because it is a kind of plant with the same origin of medicine and food, so it won't do much harm to really eat it, but it has a strong taste, which makes people feel uncomfortable after eating it, so it is very important to recognize it.

Although the third one is a little faded, it is indeed Toona sinensis. After picking it, you can use the well-known recipes to make it. After all, there are only ten days of such food every year, and its smell is very unique, so you can smell it by smell. Of course, you have to eat a serious Toona sinensis before you can tell it.

The fourth one is Azadirachta azedarach. The whole tree of Azadirachta azedarach is harmful to liver function, which will cause chronic liver poisoning. It is a fatal food for some people whose livers are not good, but ordinary people only eat one or two meals, which has little effect. However, if people in rural areas eat it wrong all season, the problem will be very serious.

second, don't eat too much.

Anything should not be ingested in excess, because drinking too much water may lead to water poisoning, and eating too much Toona sinensis will of course have adverse reactions.

First of all, the content of nitrite in Toona sinensis is much higher than that in other vegetables. If you eat too much, it will cause too much ammonium nitrite in your body, and the risk of cancer is higher if you eat it for a long time. Although the time of fresh Toona sinensis is short in season, some people will make it into pickles, and its nitrite content will be higher.

Then, eat it tender but not old. Toona sinensis appears in the market, most of them are a little old, because the real buds are not weighed and can't be sold for much money, so when some people pick Toona sinensis, they will automatically let it grow until the leaves are green, because the taste at that time is still tender and won't affect much, but in terms of nitrite content, it is two or three times more than Toona sinensis in the bud stage, so if conditions permit, it is best to eat it without green.

Generally speaking, Toona sinensis as a delicacy can be eaten properly, but it is not good to eat too much.
