A colleague's joke revealed how differently three men talk about Japanese tengsu

That day at lunch, the department ordered boxed meals, and everyone crowded into the break room. Lao Chen took two bites of rice and suddenly blurted out, "Have you guys ever heard of that Japanese health supplement, the one with a name that sounds like Chinese medicine?" He didn't say the full name, just made a gesture. A-hao, sitting across from him, immediately chimed in, saying his cousin had seen a whole shelf of them at a drugstore in Japan, with dense writing all over the packaging. His cousin couldn't read Japanese, so he took a photo and came back to ask around, but even after asking three group chats, no one could say for sure. The youngest intern, Xiao Jie, said he'd scrolled past quite a few unboxing posts on social media, and the comment sections were a mess—some said their elders had taken it for a long time, others said it was just a scam. After reading, he only felt there was a huge amount of information, but not a single sentence he could take to ask someone.

I sorted through what I'd heard at that meal in my head and realized the three versions didn't actually conflict—they were just standing in different positions: Lao Chen was talking about "having heard of it," A-hao about "having seen the packaging," and Xiao Jie about "having seen discussions." All three are far from "understanding." What really alerted me was that by the end, their tones all became the same—as if just knowing the name meant knowing what it is, whether it can be taken, and whether it should be bought. This leap is especially common with health supplements, because there are so many products and the names often mix foreign languages or traditional Chinese medicine terms, making it easy to fill in the story just from the words.

That night at home, I broke down what I'd heard point by point. The first point was "if it's from Japan, it's stricter." That statement itself has no basis—place of origin doesn't equal review standards. Countries have different classifications and labeling rules for health supplements, and the same product may fall into different categories in different markets. Whether it can be legally sold locally and whether it can claim efficacy are two different things. The second point was "someone took it for a long time and had no problems." That's just personal experience, and the definition of "no problems" is very vague—no one knows what else that person was taking, whether they had regular checkups, or whether they'd shown the list to a professional. The third point is the most troublesome: "a lot of people online recommend it." That represents volume, not data.

Later, I started treating these kinds of names as a "term to be looked up" rather than a "known answer." The specific approach is to first write down the name and confirm whether it's classified as food, a health supplement, or a drug, because these three are regulated differently in Taiwan. If it's a drug, it involves whether a prescription is required; if it's food, you can't understand it through the lens of therapeutic claims. Then look at the ingredients, warnings, target users, and usage recommendations on the packaging or official labeling—not the adjectives in reseller posts. Finally, write down "what I'm taking" as a list, including medications and health supplements currently in use, and take it to ask a doctor or pharmacist, letting a professional judge against the list rather than against online comments.

During the process, I also noticed that many people aren't actually trying to buy—they're trying to understand what they're asking about. Names like "Japanese tengsu" are easily told in several different versions partly because they involve cross-border purchasing, product classification, and individual constitution all at once. If any link isn't clear, the conclusion will be skewed. Instead of rushing to ask "does it work," it's better to first ask "what category does it fall under in my country, where did the information in my hands come from, and who should I take this information to?" Once these three questions are answered, many arguments that seemed irreconcilable will automatically separate into layers: which are rumors, which are verifiable labeling, and which can only be answered by professionals based on individual circumstances.

The next day, I explained this sequence to Lao Chen. He was stunned for a moment and said he'd originally just wanted to confirm "whether he could buy it as a gift for his elders." I replied that gift-giving actually requires more caution, because the recipient might be taking medication or have a chronic illness. If what you give is food, the person might think it's no big deal and just eat it; if it's a drug, it definitely shouldn't be recommended between colleagues. A-hao added that the photo of the shelf his cousin took was so blurry that even the price tags were unclear—you couldn't tell what product it was at all. Xiao Jie said he was going to unfollow those unboxing accounts, because he realized that after watching, he only remembered "it seems very popular" but couldn't name a single piece of verifiable information.

This made me rethink the order of "information sources." The outermost circle is chats and social media—fast, emotionally charged, but with almost nothing verifiable. One circle in is product pages and packaging—at least you can see labeling and warnings, but you need to check whether it's marketing copy or legally required labeling. Further in is officials and professionals—this circle is the slowest, but it's the best at giving suitable reminders based on your personal medication and health situation. Most people get stuck in the outermost circle because it's the easiest to access and the easiest to make people think they already understand. Reverse the order—ask professionals first, then look back at products and discussions—and a lot of anxiety will be cut in half.

That meal ended without a conclusion, and it didn't need one. Lao Chen said he'd go home and first ask his elders what they usually take. A-hao said he'd ask his cousin to delete that photo so it wouldn't be forwarded again. Xiao Jie said that next time he saw a similar name, he'd write it down first and then look up its classification, rather than hitting like first. My own takeaway was that when facing a name that's been told in several versions, the most practical action isn't to pick a side, but to reduce it to a few verifiable questions: what category does it belong to, what does the labeling say, and who should I take this list to ask? Once these steps are done, the rumors at the lunch table remain just rumors—they won't become decisions.

If you also hear a name being described vividly in the break room or a group chat, you might as well treat it as a verification exercise first. Write down the name, confirm its classification, read the labeling, organize a list of the medications and health supplements you're currently using, and then talk to a doctor or pharmacist. This process doesn't guarantee what you'll buy, nor does it guarantee any effect, but at least it lets you know what you're asking and where to ask when facing the next name that's been talked up beyond belief.
