Using Food As Medicine: For When You Start To Feel Sick

Your throat feels a little scratchy. Your energy takes an unexplained vacation. You sneeze once and immediately begin mentally rearranging your entire week. UGH, you might be getting sick.

Before you declare yourself unavailable until further notice, there are a few things you can do to support your body.

When you’re starting to feel under the weather, food can be one of the simplest ways to give yourself some extra TLC. Think fresh ginger, lemon, garlic, warming soups, raw honey, and traditional botanicals with some genuinely interesting science behind them.

In Traditional Chinese Medicine (TCM), supporting your body when you’re feeling under the weather isn’t just about what you add to your plate, but what you temporarily take off it, too. Practitioners often recommend limiting foods thought to contribute to “dampness,” such as greasy or heavily processed foods, excess sugar, and sometimes dairy, in favor of warm, cooked, easy-to-digest meals like soups, broths, and steamed vegetables. The idea is to support digestion and balance while your body focuses on getting back to feeling its best.

No, a mug of tea won’t single-handedly defeat every pathogen in existence. But staying hydrated, eating nourishing foods, getting enough rest, and supporting your body while your immune system does its job are all worthwhile places to start.

Consider this your cozy little guide to food as medicine, with recipes worth keeping in your back pocket before cold season comes knocking.

1. Fresh Ginger, Lemon & Honey Tea

Let’s start with the classic. There’s a reason some version of this combination has been passed down through generations. It’s warming, soothing, hydrating, and wonderfully simple to make.

Why we love it:

• Ginger contains bioactive compounds that have been studied for their antioxidant and anti-inflammatory properties.
• Lemon provides vitamin C, which plays an important role in normal immune function. Your body needs adequate vitamin C to keep its defenses working properly.
• Raw honey coats and soothes an irritated throat. Research suggests honey can help relieve cough symptoms, particularly at night. It is also antibacterial, antimicrobial AND and antioxidant that can help calm local inflammation.

Recipe: The Feel-Better Elixir

Ingredients

• 1–2 inches fresh ginger, thinly sliced
• Juice of ½ a lemon
• 1–2 teaspoons raw honey
• 1–2 cups filtered water
• Optional: a pinch of cinnamon or a few fresh mint leaves

Directions

1. Add the sliced ginger to a small pot of water and simmer for 10–15 minutes.
2. Remove from the heat and let it cool slightly.
3. Stir in the lemon juice and honey.
4. Sip slowly while enjoying the rare luxury of sitting down without multitasking.

Pro tip: Add the honey after the tea has cooled a little rather than boiling it. You’ll preserve more of its delicate flavor, and the finished drink will be easier on a sore throat.

Drink it warm throughout the day as desired.

2. Garlic: Nature’s Little Immune-Supporting Powerhouse

If there’s one ingredient that deserves a permanent spot in your cold-season kitchen, it’s garlic. And we’re not talking about one lonely clove buried in your pasta sauce.

Garlic (Allium sativum) has been used in traditional medicine across cultures for thousands of years. Ancient Egyptians, Greeks, and practitioners of traditional Indian medicine all valued garlic for its medicinal properties, using it for everything from digestive complaints to respiratory ailments. It’s one of those old-school remedies that has managed to stick around for a very good reason.

So what makes garlic so special?

A lot of its reputation comes down to allicin, a powerful sulfur-containing compound that forms when fresh garlic is crushed, chopped, or minced. Allicin is responsible for much of garlic’s distinctive smell and has demonstrated antimicrobial activity in laboratory settings. Garlic also contains other sulfur compounds and antioxidants that herbalists and holistic practitioners value for their potential role in supporting the body’s natural defenses.

In traditional herbalism, garlic is considered a warming, stimulating herb. It’s often used at the first signs of a cold, particularly when someone starts experiencing congestion, a scratchy throat, or that familiar feeling that something is brewing. Herbalists have traditionally incorporated fresh garlic into broths, teas, honey preparations, and food-based remedies as a way to support the body during seasonal illness.

Garlic is also valued for its broader wellness properties, including supporting healthy circulation and helping the body manage oxidative stress. It’s a wonderfully accessible medicinal food that costs very little, is easy to incorporate into everyday meals, and has a history of traditional use that spans generations.

One of our favorite ways to use it? Fermenting fresh garlic in raw honey. You get the pungent goodness of garlic paired with honey’s naturally soothing qualities. It’s a classic kitchen remedy that’s worth making ahead of cold season.

Recipe: Fermented Garlic Honey

Ingredients

• Peeled fresh garlic cloves
• Raw, unpasteurized honey
• A clean glass fermentation jar

Directions

1. Peel enough garlic cloves to fill approximately half your jar.
2. Lightly crush or score the cloves to expose more of their surface and activate the allicin-producing process.
3. Pour raw honey over the garlic until completely covered.
4. Follow a tested food-safety fermentation recipe for the correct proportions, fermentation conditions, and storage instructions. Don’t assume that bubbling or a particular fermentation period makes homemade garlic honey safe.
5. Once prepared according to safe instructions, enjoy the garlic and honey in dressings, marinades, or other recipes.

A few extra tips:

• Crush or chop garlic and let it sit for about 10 minutes before adding it to cooked dishes. This allows time for the allicin-producing enzymatic reaction to take place.
• If you’re using garlic specifically for its traditional wellness properties, consider incorporating some fresh, raw garlic into your meals when tolerated.
• Add minced garlic to homemade chicken soup, vegetable broth, or a honey-lemon dressing for an easy everyday boost.

There’s a reason garlic has been a staple in traditional medicine cabinets for thousands of years. Sometimes the most interesting wellness ingredients aren’t exotic or expensive. They’re sitting right there in your kitchen.

3. Black Seed Oil: An Ancient Botanical Worth Knowing

If you’ve followed TONIC for a while, you already know black seed oil has a special place in our formulations. But this ingredient has a story that stretches far beyond the supplement shelf.

Black seed oil comes from Nigella sativa, a flowering plant also known as black cumin. Its small black seeds have been used in traditional Middle Eastern, North African, and South Asian health practices for thousands of years. Historically, the seeds and oil have been used both internally and topically for a wide range of concerns, including digestive discomfort, skin issues, and symptoms associated with colds.

In Arabic tradition, black seed is sometimes called Habbah Sawda, or the “seed of blessing.” Its long history of traditional use is part of what has prompted modern researchers to investigate its active compounds.

One of the most studied is thymoquinone, a phytochemical found in black seed oil. Research has explored its antioxidant, anti-inflammatory, and antimicrobial properties, as well as its potential effects on pathways involved in immune function.

What does the research say? A randomized, double-blind, placebo-controlled study published in Frontiers in Nutrition in 2023 investigated a concentrated black cumin oil extract (Nigella sativa) in 72 healthy adults over 90 days. Researchers found significant increases in two important immune-related antibodies, IgG and IgM, compared with placebo, along with improvements in certain immune cell markers, including CD4+ T cells. These findings suggest that black seed oil may help support aspects of normal immune function, making it an exciting botanical for further research. While the study didn’t specifically investigate cold prevention or treatment, its positive results add to the growing interest in black seed oil’s immune-supporting potential.

Read the study: A proprietary black cumin oil extract (Nigella sativa) modulates stress-sleep-immunity axis safely (2023).

The takeaway: Black seed oil has a long history of traditional use and promising research into its biological activity. Human evidence for immune-related benefits is still developing, so it’s best thought of as a potential complement to healthy habits, not a substitute for proven medical care.

5. Make a Nourishing Garlic & Ginger Soup

When your appetite is a little off, a warm bowl of soup can be an easy way to get fluids, vegetables, and protein in one comforting meal.

Garlic and ginger bring flavor and plant compounds, while the broth helps with hydration. Add vegetables and a protein source, and you’ve got something more substantial than a mug of hot water with good intentions.

Recipe: The Cozy Recovery Bowl

Ingredients

• 1 tablespoon olive oil
• 3–4 garlic cloves, minced
• 1 tablespoon freshly grated ginger
• 1 carrot, sliced
• 2 celery stalks, chopped
• 6 cups chicken or vegetable broth
• 1–2 cups shredded cooked chicken, or white beans if you eat legumes
• 1 cup chopped spinach or kale
• Juice of ½ lemon
• Salt and black pepper, to taste
• Optional: fresh parsley, dill, or chopped scallions

Directions

1. Warm the olive oil in a soup pot over medium-low heat.
2. Add the garlic and ginger and cook briefly, until fragrant.
3. Stir in the carrot and celery, then add the broth.
4. Simmer for 15–20 minutes, until the vegetables are tender.
5. Add the cooked chicken and greens and simmer until heated through and wilted.
6. Finish with lemon juice, fresh herbs, and seasoning to taste.

Why it works as a feel-better meal: It provides fluid, protein, and a variety of nutrients from vegetables. The warm broth may also feel soothing when your throat is irritated or your nose is congested.

You can make a batch ahead of time and refrigerate leftovers promptly, so there’s something nourishing waiting when cooking feels like an unreasonable request.

6. Make a Citrus & Berry Smoothie

Not everyone wants soup when they feel sick. Sometimes a cool, easy-to-drink smoothie is more appealing, especially when your appetite is low.

Vitamin C supports normal immune function, and berries and citrus are delicious ways to get it through food.

Recipe: The Bright-Side Smoothie

Ingredients

• 1 orange, peeled
• ½ cup frozen strawberries
• ½ cup frozen blueberries
• ½ banana
• ¾–1 cup water or unsweetened milk of choice
• Optional: a small piece of fresh ginger

Directions

Blend everything until smooth, adding more liquid as needed.

For a more filling smoothie, add a scoop of protein powder you tolerate well or serve it alongside eggs, toast, or another protein-rich snack.

Getting nourishment in a form that sounds appealing is definitely a win when you’re not feeling your best.

7. The Most Underrated Ingredients: Rest, Fluids & Common Sense

It’s tempting to search for the one food, herb, or supplement that will make a cold disappear overnight. Unfortunately, the immune system doesn’t come with a convenient reset button.

The basics still matter:

• Hydrate regularly. Water, broth, and warm tea can help you maintain fluid intake, especially if you have a fever.
• Eat enough. Include protein, fruits, vegetables, and other foods that provide the nutrients your body needs.
• Prioritize sleep. Give yourself permission to cancel the optional things and rest.
• Take precautions around others. If you have respiratory symptoms, consider testing when appropriate and stay home when you’re sick.

Seek medical advice if symptoms are severe, worsening, persistent, or accompanied by difficulty breathing, chest pain, dehydration, or other concerning signs.

A Little Extra Care Goes a Long Way

Food as medicine doesn’t have to mean an elaborate protocol, a cupboard full of supplements, or a recipe requiring ingredients found exclusively in a remote mountain village.

Sometimes it’s a mug of ginger-lemon-honey tea. Sometimes it’s a pot of soup that lasts three days. Sometimes it’s making a little room in your schedule to rest instead of pushing through every obligation.

Black seed oil is another traditional botanical worth knowing, with emerging research into its antioxidant, inflammatory, and immune-related effects. Flex TONIC can help too.

The goal isn’t to control every sniffle. It’s to take good care of yourself, give your body what it needs, and make the process of feeling better a little more comforting.

Here’s to warm mugs, nourishing meals, and taking the hint when your body asks you to slow down😉
