Stinging Nettle Tea (イラクサ) vs Benifuki Tea

About Stinging Nettle Tea

Stinging nettle tea comes from nettle shrubs that are native to Eurasia but are widely distributed throughout all the temperate regions of the world. The benefits of stinging nettle tea have been known as early as ancient times, when ancient Egyptians reportedly used the infusion for the relief of arthritis and lumbago, while Roman troops and English were said to wash themselves with stinging nettle to keep themselves warm.

To make stinging nettle tea, the leaves, stem, or root from the stinging nettle plant are crushed and then dried, which can also be done with the nettle's flowers. This type of tea is a staple in Western countries. Like any other tea, stinging nettle tea can be bought loose or in teabags, but you can also grow or harvest the leaves yourself. On how to prepare your stinging nettle tea with fresh leaves, the preferred method is by adding two cups of water for every cup of leaves and bringing the water just to a boil. Turn off the stove and let the tea sit for five minutes, then pour the mixture through a strainer. An option is to add a bit of honey, cinnamon, or stevia, if you like.

Stinging Nettle Tea

The plant itself has heart-shaped leaves and yellow or pink flowers, but the stem is covered in tiny, stiff hairs that release stinging chemicals when touched. Its scientific name is Urtica dioica, with a genus name from Urtica, which is derived from uro, meaning to burn, or urere, meaning to sting, while the stinging nettle species name dioica is Latin for "two houses", from the Greek word oikia, meaning house, and refers to the plant’s dioecious nature, bearing male and female flowers on separate plants.

Stinging nettle tea has lots of medicinal benefits and uses and is considered to help as a diuretic, antihypertensive, anti-diabetic, hemostatic, anti-asthenia, anti-anemic, antispasmodic, antirheumatic, for headaches and chills, as well as treatment for spleen, renal, and dermal disorders. Stinging nettle teas are also being used as treatments for rhinitis and seasonal allergies. They are also used as a treatment for anemia thanks to their high content of iron and trace elements.

In modern times, stinging nettle tea may help flush harmful bacteria from the urinary tract. Also, the Arthritis Foundation suggests that stinging nettle tea may also reduce the inflammation and pain associated with osteoarthritis. As a beauty case, stinging nettle teas also contain potent antioxidants, which are substances that protect the body from aging and cell damage.

About Benifuki Green Tea

Benifuuki, on the other hand, is also considered an herbal green tea that is primarily used as an anti-allergy, having the highest concentration of catechins of all green teas. This tea has a high concentration of a special variety of catechin called methylated epigallocatechin gallate, which works in the body to block histamines. This tea is also helpful against hay fever, atopic dermatitis, eczema, histamine reduction, improved metabolism, liver function, and weight loss. This cultivar was originally meant for black tea and oolong but is now also being processed as green tea. Benifuuki, however, contains only a relatively small number of other important nutrients that are found in any other Japanese green tea; therefore, Benifuuki tea is rather considered a specialist addition to the traditional Japanese green teas for health benefits.

While stinging nettle tea has been used popularly since ancient times,  benifuuki tea is a special cultivar of Japanese green tea that was introduced in the Japanese market by Japanese breeders only in 1993. Benifuuki is actually a hybrid plant that was a byproduct of crossbreeding Benihomare, an assamica variety that is mostly found in India and Sri Lanka, with MakuraCd86, usually coming from India but a sinensis variety that is popular in China and Japan, in Makurazaki city, Kagoshima prefecture, in 1965. The right seedling was selected after so many years and registered only in 1993. It was originally developed as a mellow, aromatic black tea, but it was thereafter discovered that it could be harvested as a green tea health beverage. It literally means "red riches and honor" in Japanese. Being a Camellia sinensis species, it is also sometimes called the "Japanese oolong".

Benifuki Tea

Its flowers and leaves are larger than the more popular cultivar for Japanese green tea, which is the yabukita. Banifuuki leaves have three stems. The tea is not shaded because the sunlight allows for a higher catechin content, is easily fermented, and provides a 30% higher yield than the Yabukita tea plants. Benifuuki leaves are also easy to plant and harvest since they show a particularly high resistance to disease and can be grown using only very small quantities of pesticides. Tea plants in Japan are usually prone to many diseases and pests, but the Benifuuki tea plant is highly resistant, such that farmers use fewer pesticides on it, with substantially fewer harmful residues in the Benifuuki green tea.

It has a clearly bitter and strong flavor. The final processing of harvested leaves does not occur immediately, unlike other normal Japanese green teas. Benifuuki leaves are usually stored for around 3 months and fermented in the dark at low temperatures. Only thereafter can the usual further processing, just like any ordinary Japanese green tea, be done by intensive hot steaming, rolling, and pressing of the leaves; thus, the best benifuuki tea to buy is that harvested a season before. For example, in early 2020, one should look to buy tea from the 2019 autumn harvest.

Benifuki Tea

Benifuuki also comes in powder or loose-leaf tea varieties. In Japan, Benifuuki is taken as a powder in combination with tea since the catechins and bitter substances are relatively poorly soluble in water. However, the advantage of benifuuki loose tea leaves is that, in a relatively short period of time, the powder becomes toxic after preparing it and should be consumed right away. On the other hand, the benifuuki loose tea leaves allow for a longer shelf life and can still be refrigerated for a few days.

FAQs about Stinging Nettle vs Benifuuki Tea

Are stinging nettle tea and benifuuki tea actually similar — they're both for allergies?

Both are used for allergy support but they work through completely different mechanisms. Stinging nettle (Urtica dioica) is an herb (not a tea plant) that contains compounds — particularly histamine and quercetin — that have been shown to mildly reduce hay-fever symptoms. The traditional use is brewed as a tisane (herbal infusion) and drunk during allergy seasons.

Benifuuki (べにふうき) is a Japanese green tea cultivar with unusually high methylated catechin content (specifically EGCG3″Me), which stabilizes mast cells and reduces histamine release. The mechanism is different from nettle's — benifuuki targets the mast-cell mechanism upstream, while nettle modulates downstream symptoms. Benifuuki powder is the most concentrated form.

They can be used together — the mechanisms don't conflict — and some allergy sufferers report that combining nettle and benifuuki produces better results than either alone. The combo is more useful for chronic histamine intolerance than for occasional seasonal allergies.

Which is more effective for seasonal hay fever — nettle or benifuuki?

The clinical evidence is stronger for benifuuki. Multiple controlled studies show measurable reductions in seasonal allergy symptoms with daily benifuuki consumption (typically 2 cups daily for 4-8 weeks before allergy season starts). Nettle tea has positive but smaller-quality evidence — some randomized trials, more anecdotal reports, less consistent dosing.

Practically: benifuuki has a more reliable effect at predictable doses; nettle is more of a folk-medicine tradition with less standardization. If your allergies are significant enough that you want a real intervention, benifuuki is the higher-yield choice. If your allergies are mild and you want a gentle herbal support, nettle works fine.

Stacking both is reasonable. Daily benifuuki + occasional nettle during heavy pollen days produces broader coverage than either alone. Neither is a substitute for prescription antihistamines if your allergies are severe.

Does nettle tea have caffeine, and how does that affect the comparison?

No — nettle tea is a tisane (herbal infusion), not a true tea, and contains zero caffeine. That's an advantage for evening drinking and for people who can't tolerate caffeine. Benifuuki contains roughly the same caffeine as standard sencha (25-35 mg per cup), which can be an issue for caffeine-sensitive allergy sufferers.

If you specifically want caffeine-free allergy support, nettle is the cleaner choice. If caffeine is fine and you want stronger evidence-based support, benifuuki wins. The teabag form of benifuuki is lower in caffeine than the powder form, which gives a middle ground.

There's also a hojicha-benifuuki blend approach that some Japanese tea brands offer — the high-temperature roasting of hojicha reduces caffeine while keeping some methylated catechin support. Less common in the U.S. market but worth knowing about.

Can I drink nettle tea and benifuuki on the same day?

Yes, no negative interaction. The mechanisms are different and complementary. A practical schedule: benifuuki in the morning (when caffeine is welcome), nettle in the afternoon or evening (caffeine-free). Keeps both compounds in the bloodstream throughout the day and respects sleep timing.

Most users who combine them report better symptom control during heavy pollen days than either alone produces. The combination doesn't appear to have any redundancy issues — each tea targets a different aspect of the allergic response.

Watch the total caffeine if you're stacking benifuuki with other green teas (sencha, matcha) too. The caffeine math adds up across multiple cups; benifuuki + matcha + sencha can exceed 200 mg/day caffeine if you're not paying attention. Adjust intake accordingly.

Are there other natural antihistamine options I should know about?

A few worth mentioning. Quercetin (found in onions, apples, capers, and as a supplement) is one of the most-researched natural antihistamines — works through a similar mast-cell-stabilizing mechanism as benifuuki's methylated catechins, just less potent per dose. Often taken as a 500-1000 mg supplement during allergy season.

Bromelain (from pineapple) and butterbur extract both have some clinical evidence for allergy support. Vitamin C at high doses (1-2g daily) has mild antihistamine effect. Local honey is more folk-medicine than evidence-based but tastes good and doesn't hurt.

The strongest approach is usually combination: benifuuki tea + quercetin supplement + local honey + regular exercise (which itself reduces allergic inflammation) is more effective than any single intervention. None of this substitutes for medical treatment if your allergies are severe enough to warrant prescription antihistamines or immunotherapy.
