Dyed Plants: Hidden Harm Beneath a Pretty Appearance, Buy with Caution
At flower and bird markets we see many dyed plants and flowers, brightly coloured and very pretty, especially eye-catching to children. Many parents, unable to resist their children's pleading, casually buy a pot and take it home to grow, little knowing that these dyed plants are not only bad for the plants' growth, but may also bring adverse effects to their owners. So what exactly is going on?
Dyed Cacti Are Hugely Popular
In recent years, to cater to young people's pursuit of novelty, a brand-new kind of "dyed" cactus has appeared out of nowhere and was once hugely popular. This "dyed" cactus is different from the traditional "natural-coloured" cactus, which is not green all over. On the contrary, the "dyed" cactus is only dyed at the top, showing various colours, but some are "colour-changed all over", that is, the whole body is sprayed with colour so that all the spines become a new colour. Viewed from a distance, the "dyed" cactus is a riot of colour and is sought after by many young people, most of whom buy it to beautify their office or home environment.
It is understood that this "dyed" cactus sells quite well in some online shops and some flower and bird markets. Because the bright colours easily catch people's eyes, many young people are keen to take these brightly coloured, dazzling cacti home, or place them on their desks, or give them to relatives and friends, adding a touch of vibrant colour to life.
Can Dyed Cacti Affect Health?
Regarding the colourful cacti, some members of the public wonder: can dyed cacti have adverse effects on the body? Many people buy cacti to put on their desks in the hope that the cactus will resist computer radiation, but does a dyed cactus still have this "effect"? Will "dyed" cacti affect health?
On this point, our editor also checked relevant information and learned that the "dyed" cacti currently popular on the market not only damage the plants themselves, but are also bad for human health. Some experts analyse that the cactus is a plant with a very good original ecology, and after being artificially dyed with pigment, not only is the cactus's growth hindered, but the pigments and toxicity in the dye may more or less have some adverse effects on the human body. For example, dyeing a cactus is like coating a layer of paint on human skin; this practice will inevitably hinder its own secretion and hinder the plant's growth.
Experts suggest that members of the public should preferably buy natural cacti in their natural colour. The cactus itself has good colour and growth form, and "dyeing" is an unnecessary practice.
When Admiring Tulips, It Is Best Not to Exceed Two Hours
In spring, people go out to enjoy the greenery and flowers, but many complain after returning from flower viewing: for some unknown reason, uncomfortable symptoms such as dizziness, blurred vision and sneezing occur frequently. On this point, senior engineer Wu Zhixing says that tulips are very beautiful in appearance, but they release an alkaloid, and this alkaloid has side effects on the human body. If you stay among tulips for a long time, you may feel unwell, and may even experience hair loss, including hair and eyebrows.
Based on the characteristics of tulips, botany experts remind the public that enjoying flowers and relaxing in spring is certainly a good thing, but flower viewing also requires a sense of "moderation", and time needs to be controlled. Generally speaking, it is not advisable to linger too long among tulips; it is best to keep it within two hours at a time. Experts stress that as long as flowers are enjoyed within the specified time, there will generally be no effect on the human body, and the public need not blindly avoid tulips. But if you greedily cling to the beauty of tulips without limit, even weaving in and out among the tulips uncontrolled, staying too long and taking photos, then their alkaloid may cause harm to the human body.
Experts suggest that one flower-viewing session should preferably be two hours, but if you are especially fond of tulips, it is recommended to use a "go again after a few days" approach of "several times, short each time", which can avoid the possible harm of tulip alkaloids to the human body.
