If you've shopped for Essiac tea, you've probably run into the brand name Flor Essence and wondered whether it's the same thing—or something better. Here's the short answer: both are built on the same eight-herb formula. The differences that actually matter come down to how the tea is sold, how it's prepared, and what you pay for it.
A Quick Note
Essiac tea is a traditional herbal beverage. It is not intended to diagnose, treat, cure, or prevent any disease, and these statements have not been evaluated by the FDA. Always talk to your healthcare provider before adding any herbal product to your routine, especially if you have a medical condition, are pregnant or nursing, or take medications.
The Shared Origin Story
Both formulas trace back to René Caisse, the Canadian nurse who spent decades refining an herbal tea recipe. ("Essiac" is Caisse spelled backwards.) She was originally given eight herbs, and over years of research she worked out the ratios she felt worked best. Later, Caisse and Dr. Charles Brusch developed the full eight-herb formula that became known—and trademarked—as Flor Essence. The same eight-herb tea is what reputable Genuine Essiac sellers offer today.
The same eight herbs
Both Genuine Essiac and Flor Essence contain the same eight herbs:
- Burdock root
- Sheep sorrel
- Slippery elm bark
- Turkish rhubarb root
- Watercress
- Blessed thistle
- Red clover
- Kelp
The formula is synergistic—the specific combination and ratios are what matter, not any single herb. This is also why the eight-herb blend is considered the most complete formula.
In her research, Caisse concluded the eight-herb tea outperformed four-herb versions, and that was her final recommendation. Some companies still sell only four herbs; that's the older, incomplete formula. If you are looking for the most powerful option, be sure to confirm that all eight are listed.
So what's the difference between Flor Essence and Essiac tea?
Since the herbs are the same, the real differences between Flor Essence and Genuine Essiac are practical:
Price. This is the big one. Flor Essence is typically sold as a pre-made liquid at a premium price, often only a couple of weeks' worth at a time. Buying loose herbs and brewing it yourself costs dramatically less—often under $1 per day—which is exactly why many people switch. While Flor Essence offers a powdered version too, even that option costs many times more than what you would pay for a brand like Genuine Essiac.
Form. Flor Essence usually comes ready-to-drink in a bottle. Genuine Essiac is exclusively sold as loose, powdered herbs that you brew at home in a large batch (typically a gallon), store in the fridge, and drink cold in small servings (about 3 oz. at a time).
Powdered vs. whole herbs. Powdered herbs have more surface area, so they make a more potent brew and let you consume the fine herb particles along with the tea—just as Caisse recommended. You're not able to consume the powdered herbs when you use pre-bottled tea.
Quantity and value. Because you're buying the herbs rather than the water and packaging, a single purchase of loose herbs can last months instead of weeks, which stretches your dollar much further. Genuine Essiac is sold in the smallest sizes being 1 lb. of herbs. The bulk pricing is designed to save you money. Flor Essence powder is typically sold in 6 oz. portions and naturally costs more per ounce.
Side-by-Side Comparison
| Genuine Essiac (powderd herbs) | Flor Essence (liquid) | |
|---|---|---|
| Herbs | Same eight | Same eight |
| Form | Loose powdered herbs you brew | Pre-made liquid |
| Prep | Brew a batch at home, refrigerate | Ready to drink |
| Cost | Often under $1/day | Typically much higher |
| Supply per purchase | Months at a time | Often a couple of weeks |
Which should you choose?
If convenience is your top priority and cost isn't a concern, an already brewed product like Flor Essence could be a good option.
If you want the same eight-herb formula for a fraction of the cost—and you don't mind spending about ten minutes to brew a two-week supply—loose powdered Genuine Essiac gives you far more tea per dollar and lets you consume the herb particles along with the tea, the way Caisse intended.
How to Shop Smart for Essiac
- Confirm that the blend contains all eight herbs. Genuine Essiac and Flor Essence both list eight. If a product shows only four, it's the older formula.
- Compare cost per day, not just sticker price. A bottle that lasts two weeks vs. a bag that lasts months is not an apples-to-apples comparison.
- Favor powdered loose herbs whenever possible so you get a more potent brew and can consume the herb particles.
- Buy from a source that regularly tests each batch for herb quality and can provide a Certificate of Analysis.

The Bottom Line
Flor Essence and Genuine Essiac are the same eight-herb formula. If you want convenience in a bottle, Flor Essence delivers it. If you want that same formula for far less—brewed fresh at home from powdered herbs—Genuine Essiac is the better value. Either way, make sure you're getting all eight herbs, compare the true cost per day, and buy from a source that stands behind its quality.
