Q&A: This London market and eatery is all about ginseng
London market and eatery Jing Jing Nutrifood Inc. is the passion project of Edmund (Ed) Lui, a retired professor of physiology and pharmacology at Western University. Jing Jing, which translated to essence and life energy, offers an array of ginseng products such as drinks, capsules, tinctures, soups and even maple syrup, along with a licensed restaurant.
The CBC's Travis Dolynny stopped by the unique shop at 85 York Street to talk to Lui about his story and passion for the "king of herbs."
The following has been edited for length and clarity:
Travis Dolynny: Ed Lui, tell me a little bit about yourself. What's your background, and why ginseng?
Ed Lui: I was trained as a pharmacologist and toxicologist at Dalhousie University, but I also have a family background in traditional Chinese medicine. My father had been engaged in making proprietary tonic medicines for many years, so you could say it's built into my genetics.
After graduation, I spent some time in the United States at the National Institutes of Health before returning to Canada, where I worked with the Department of Physiology and Pharmacology at Western University for many years. I retired several years ago.
As for ginseng, my background in Chinese medicine led me to recognize its long history of use. In 2008, the Ontario government announced funding to promote interdisciplinary research and enhance commercialization by integrating academia with the private sector. I saw ginseng as a great candidate for this initiative because North American ginseng is grown here in Ontario—it is the largest producer of American ginseng in the world. However, most of it is exported to China, and we end up importing the finished products back into Canada.
I thought a research project aimed at enhancing commercialization and increasing the value of Ontario-grown American ginseng could change that. So, I created a consortium for innovation and research, securing a $20 million project to develop new agricultural technology and new product development for American ginseng.
TD: What is it about ginseng that is so beneficial?
EL: It's quite interesting. Traditionally, ginseng has been called a panacea—a cure-all. It was even referred to as the "King of Herbs" and was so valuable in ancient times that only royalty could afford it.
Looking at the research, we found that ginseng contains numerous compounds that work together synergistically, targeting multiple biological processes. This is different from modern pharmaceuticals, which typically involve a single molecule targeting a specific receptor. Traditional Chinese medicine takes a broader approach, examining how different components in an herb interact to create a wide range of effects. Ginseng, for example, can support the immune system, reduce inflammation, and improve metabolic health.
TD: So, ginseng has healing properties?
EL: Yes. Our studies examined its role in immunomodulation, anti-inflammatory properties, cardiovascular health, and even erectile dysfunction. We also looked at how it prevents ischemia-reperfusion injury, supports heart function, and affects metabolic syndrome.
TD: Are there any side effects?
EL: It depends on the individual. Some people may be more sensitive to ginseng, experiencing mild stimulation or difficulty sleeping. Generally, however, we don't see significant adverse effects. People taking medications should be cautious, as herb-drug interactions are always a possibility. While research hasn't shown major interactions with ginseng, we recommend taking it at least two hours after medications to minimize any potential effects. For those on blood thinners, it's best to consult a doctor before using ginseng.
TD: What are some of the products you've developed?
EL: We've created natural health products that are approved by Health Canada. These extracts are produced from the ginseng root and have approved claims for stimulating immune function, modulating blood glucose, and calming nerves.
One of our unique innovations is advanced processing technology that allows us to convert regular ginseng into American Red Ginseng, similar to Korean Red Ginseng. This version has stronger anti-inflammatory and potential anti-cancer properties, making it more potent than regular ginseng. Many of our products are based on this enhanced version.
Besides natural health products, we also produce health foods, which don't require licensing but can't make health claims. However, we ensure high quality by using nutraceutical-grade ginseng. Some of our products include a ginseng elixir made with red ginseng and other adaptogenic ingredients like goji berry, hawthorn, cranberry, Jerusalem artichoke, and schisandra.
We've also infused coffee beans with ginseng extract to provide an additional energy boost. This is especially beneficial for people who can't tolerate caffeine but still want a natural stimulant.
TD: How do you incorporate ginseng into your life?
EL: Oh, I have it every day. I take one capsule a day as a natural health product. Then, we have the elixir and the thirst quencher. Since there's only so much ginseng you can take at one time, using multiple products ensures you get enough to experience its full benefits for health and wellness. So, I'm definitely a proven guinea pig!

Seven hospitalized after eating salami recalled due to possible salmonella
Seven people have been hospitalized after eating salami recalled due to possible salmonella contamination. The Public Health Agency of Canada released a notice Wednesday stating that 57 people — 44 in Alberta and 13 in Ontario — got sick after eating Rea brand Genoa Salami Sweet, Rea brand Genoa Salami Hot and Bona brand Mild Genova Salami. The federal agency said most people were ill between mid-April and late May, after eating salami in prepared sandwiches or bought from deli counters. Products were also distributed at grocery stores, specialty markets, restaurants, cafes, delis and butcher shops. The Canadian Food Inspection Agency recalled the products in Ontario, Alberta and Manitoba on June 10. They recommend checking for the following product codes: 5035 226, 5049 226, 5020 228, 5035 228 and 5035 226. Salmonella is a food-borne bacterial illness that can spread several days or weeks after a person is infected, even if they don't have symptoms. It can result in severe and potentially deadly infections, particularly for children, pregnant people, the elderly and people with weakened immune systems.

Ottawa Public Health defends decision to reduce water testing at beaches
Social Sharing Ottawa Public Health is defending its decision to reduce its testing of the city's beach water, amid criticism that doing so makes swimming riskier. Until this swimming season, OPH has tested beach water quality daily but announced last month it would reduce testing to once a week starting June 21 to align with provincial standards, following a review of its beach water monitoring program. According to Matthew Ruf, the Safe Food and Water Program manager with OPH, the shift will allow swimmers to pay attention to other factors when determining if it's safe to take a dip. "We want people to broaden that horizon and think about those things that we can prove that are well known in science, and impact water quality," said Ruf. Being aware of recent heavy rainfall, dead fish, algae and cloudy waters are all better indicators of water safety, he said. Daily testing can offer misleading information, he said, because it takes at least a day for results to come back and bacteria levels in water can change within that time period. "To have people focus in on a water result that's 24 hours old isn't real time information," said Ruf. 'A huge step backwards': Ottawa Riverkeeper But Ottawa's Riverkeeper, Laura Reinsborough, said she's "deeply disappointed" by the change. She said daily testing was the "gold standard" in the province and called the move by OPH "a huge step backwards" because it could put Ottawan's at risk of exposure to and other bacteria. "When you just look to give a visual survey of a beach, you don't know what the bacteria count is in the water," said Reinsborough. "And so right now our best information is the rough water quality testing. It takes a day, but it gives you that information as soon as it's possible to receive it." She said her organization, a local non-profit which advocates for the sustainable use of the Ottawa River, looked at the last three years of water quality data for the designated beaches and found that scaling back to weekly testing would mean that 20 per cent of test results would be "false." "That would mean either that beaches are closed on days when it would be safe to swim or that they're open on days when the test results would have shown that it was not safe for swimming that day," she said. 'Informed decisions' According to OPH, its beaches meet the water quality standard of under 200 parts per million nearly 85 per cent of the time, but when it is unsafe, Reinsborough says people need to know. "It's all about informed decisions," she said. "Both from the public and the city to open and close beaches." Earlier this week, Ottawa Riverkeeper launched a petition to reinstate daily tests, which Reinsborough said received about 400 signatures in less than than 48 hours. "We're hopeful that they'll hear that daily testing really matters to be able to make those informed decisions," she said.

Meet the doughnut disruptor of Almonte, Ontario
Is there a way to build a better doughnut? Ed Atwell thinks so. Whether he's in the fried sweet business or actually in the technology business, the Almonte, Ontario entrepreneur is all about ingenuity. The owner of Healthy Food Technologies Inc. (HFT), didn't set out to reinvent the fryer. Mr. Atwell simply wanted to make a novelty doughnut. It was called the Sunny Moon, a two-tone concoction that's half chocolate and half vanilla. He patented the doughnut about 25 years ago, and it became the inspiration for a much larger idea. Making the Sunny Moon took some creativity, as it's tough to make a 'seamless' doughnut, says Mr. Atwell. That got him thinking about frying techniques and ways to make doughnuts lighter. Fifteen years ago, he came up with a low-fat process where the dough would go into a fryer, then get transferred to an oven just before it would absorb most of the oil. He had to build a combo deep fryer and oven to pull it off. As he explains, the oil is used to 'toast' the doughnut, which then spends 60 per cent of its cooking time in the oven, which is heated to the same 375 degrees. That 'tricks' the doughnut into thinking it's still being heated by the oil, Mr. Atwell says. To describe how the dough reacts when heat is transferred, Mr. Atwell coined the term exohypothermia. With the dough no longer in oil, it stops acting like a sponge. The result is a fried product that retains its flavor and texture but contains a fraction of the fat – about 50 to 70 per cent less fat than its deep-fried counterparts. Mr. Atwell has taken a winding path through the doughnut industry. He worked in management for Country Style, and honed his skills at Tim Hortons in Nova Scotia, where he opened stores and trained bakers. 'A doughnut has its own language,' he says. After working as a consultant for the industry, he created the Sunny Moon doughnut. Later, his first attempts at designing a new baking method involved combining a deep fryer with an old pizza oven. 'I was just trying to prove a theory.' He bought a building in an industrial park in Almonte, and converted it into a doughnut-making R&D facility in 2010. During the process of perfecting his technique, Mr. Atwell had loads of doughnuts left over. So he just started giving them away to the local grocery store and police station. Eventually, he stuck a small sign outside HFT that read 'doughnuts today' and word spread. In 2013, he added a storefront. Now, his full-production doughnut shop employs 10 people. 'For the longest time we were growing at 35 per cent per year,' says Mr. Atwell. Though the COVID-19 pandemic slowed down that rate, 'We haven't lost growth either, which in these economic times is huge.' Before he opened his shop, a large doughnut manufacturer had expressed interest in buying Mr. Atwell's technology, but the deal never materialized. He says his pitch was perhaps too bold for the corporate world. 'You've been making doughnuts the wrong way for 50 years. That's a tough sell.' Still, focusing on the byproduct of the process – the actual doughnut – instead of just trying to sell or license the technology was the right strategy for HFT, says Mark Freel, a professor of entrepreneurship at the Telfer School of Management, University of Ottawa. 'Turning it into his own products is probably the best way to monetize his own technology,' says Mr. Freel, whose research focuses on innovation, and how firms create and capture value. He says that if you're a small company, like a doughnut shop in Almonte, some multinational might purchase your technology or pay you royalties for its use. But it doesn't happen often. The best thing to do is use that technology to make your own goods 'and make a great reputation doing it – that's how you make money.' HFT has a cult following in Almonte and beyond. Word-of-mouth has brought doughnut pilgrims from across Ontario. One time, a Toronto company sent an Uber driver through the night to pick up 10 dozen doughnuts for a morning meeting. 'That was probably the craziest thing we ever saw happen,' says Mr. Atwell. Devotees love the shop's lower-fat wares, yet the doughnut's appeal goes far beyond the nutritional breakdown. 'Oil gives a negative flavour after time,' says Mr. Atwell. 'But when you heat a product like bread, it enhances the flavour. So we have a product that's lower in fat, but actually has more flavour.' While he has a successful doughnut shop, Mr. Atwell still talks up his technology. Besides the flavour and low-fat benefits, he says his process can deliver significant cost savings, mainly through oil saved, and can virtually pay for itself within a year. Even though he feels like his technology can disrupt doughnut-making, Mr. Atwell is content to let the process unfold naturally. Maybe one day it will take over the commercial market. Until then, 'I look at the technology like a tree. I'll plant it and it'll grow as it wants to.'
