Varietal Honeys Beyond Manuka

Manuka honey gets most of the attention in antimicrobial honey research, and its methylglyoxal pathway is the best-studied non-peroxide system in any honey. Other honeys have been studied too. Researchers in Australia, New Zealand, Europe and North America have looked at their antibacterial, anti-inflammatory and antioxidant properties. The evidence for most of them is thinner than for manuka.

The honeys below are not substitutes for sterile medical-grade honey. Each has its own studies, and most of the evidence comes from lab work or small trials.

Kanuka Honey New Zealand

Botanical Source: Kunzea ericoides (Kanuka tree), closely related to the Manuka tree (Leptospermum scoparium). Both species are native to New Zealand and often grow in adjacent stands.

Kanuka honey has drawn research interest for skin conditions. Its main studied effect is anti-inflammatory rather than directly antibacterial, though some lab studies report antibacterial activity too.

A randomized trial published in BMJ Open in 2015 (Braithwaite et al.) tested a product made of 90 percent medical-grade kanuka honey and 10 percent glycerin against a control cream in 138 adults with rosacea. After 8 weeks, 34 percent of the honey group and 17 percent of the control group had improved by at least two points on a severity scale. The authors noted wide confidence intervals and that participants could not be blinded. It is one trial of one product, so treat it as a promising result, not a settled one.

Jarrah Honey Western Australia

Botanical Source: Eucalyptus marginata (Jarrah tree), native to the forests of Western Australia. Jarrah trees bloom every two years, making the honey a biennial harvest with limited and variable supply.

Jarrah honey is often described as having a high Total Activity (TA) rating. TA is an Australian measure of a honey's combined antibacterial effect, expressed as an equivalent concentration of phenol. Ratings vary by batch, so check the label rather than relying on a general figure.

Laboratory studies have reported Jarrah honey activity against bacteria such as Staphylococcus aureus. The activity appears to depend mainly on hydrogen peroxide, which can be sensitive to heat and light during storage.

Some sources report a lower glycemic index for Jarrah honey than for most honeys. If you manage diabetes, talk to your care team before treating any honey as a lower-sugar choice. It is still mostly sugar.

Blackbutt Honey Eastern Australia

Botanical Source: Eucalyptus pilularis (Blackbutt tree), a tall eucalyptus species found along the eastern coast of Australia from Queensland to New South Wales.

Blackbutt honey is a newer research subject. Early lab work reports antibacterial activity, but we have not found large studies, and ratings vary by batch and harvest.

The research base for Blackbutt is thinner than for Jarrah or Kanuka, and the studies we found were small. It is too early to say how it compares with other eucalyptus honeys.

Heather Honey Scotland & Northern Europe

Botanical Source: Calluna vulgaris (Common Heather or Ling Heather), native to moorlands and heathlands across Scotland, Scandinavia, and Northern Europe.

Heather honey has a long history in European folk medicine. It is thixotropic: at rest it behaves like a gel, but when stirred it becomes liquid. That gel-like texture is why it was traditionally favored for dressings, since it stays put on irregular surfaces.

Laboratory analysis reports antibacterial activity, mainly through hydrogen peroxide, and a relatively high content of phenolic compounds compared with lighter honeys. The dark color and strong flavor go with that higher content.

Buckwheat Honey North America & Europe

Botanical Source: Fagopyrum esculentum (Common Buckwheat), cultivated across the northern United States, Canada, and Eastern Europe.

Buckwheat honey is the easiest varietal on this list to find. It is produced in large quantities in temperate grain-growing regions and is sold at farm markets and specialty stores across North America. Its dark color, molasses-like flavor and strong aroma set it apart from lighter honeys.

The clinical interest centers on one pediatric trial. In a 2007 study in Archives of Pediatrics & Adolescent Medicine (Paul et al.), 105 children aged 2 to 18 with nighttime cough from a cold received buckwheat honey, the cough suppressant dextromethorphan, or nothing, 30 minutes before bed. Parents rated the honey group as improving the most, and honey was significantly better than no treatment. Honey and dextromethorphan did not differ significantly. It was a single-center study, and parents did the rating. Never give honey to a child under 12 months.

Buckwheat honey also tends to rank high in antioxidant tests compared with lighter honeys such as clover, and its dark color goes with a higher phenolic content. A lab antioxidant score does not show a health benefit in people.
