Sweet Gum Tree
The Tree Everyone Curses — and Almost Nobody Understands
If you grew up in the South, you know the sweet gum tree. You probably know it best as the source of those spiky brown balls that litter your yard every fall — the ones that twist your ankles, clog your gutters, and make you wish the tree had never been planted. What most Southerners don’t know is that the same tree they’ve been cursing for years is one of the most medicinally valuable plants in North America, with a documented history of human use going back thousands of years.
A Tree With Deep Roots in Southern Medicine
The sweet gum tree — Liquidambar styraciflua — is a native North American hardwood that grows abundantly across the Southeast, including right here in Alabama. Native American tribes including the Cherokee used the leaves, bark, resin, and seed pods to treat everything from wounds and coughs to stomach problems and inflammation. The resin of the tree, known as storax, was one of the earliest known antiseptics in the Americas and has since been shown in laboratory studies to be effective even against multidrug-resistant bacteria.
Southern folk herbalists carried that knowledge forward for generations. In Appalachia and across the Deep South, sweet gum balls and bark preparations were a standard part of the home medicine cabinet long before anyone understood the chemistry behind why they worked.
What Modern Science Found Inside
When researchers began studying sweet gum more closely, they found something remarkable. The seed pods — particularly the infertile seeds inside the green balls — are a natural source of shikimic acid, the same compound that pharmaceutical companies extract from star anise to manufacture Tamiflu, one of the most widely used antiviral medications in the world. Published research in peer-reviewed journals has confirmed that sweet gum (Liquidambar styraciflua) is a renewable domestic source of shikimic acid, with infertile seeds yielding concentrations of up to 6.5% by dry weight.
Beyond shikimic acid, research has also shown that sweet gum extracts directly inhibit the H1N1 virus by targeting neuraminidase — the same mechanism Tamiflu uses. The tree also contains terpenes, flavonoids, gallic acid, and salicylic acid compounds that have demonstrated antioxidant, anti-inflammatory, antimicrobial, and antifungal properties in laboratory studies. Extracts from sweet gum seeds have even shown anticonvulsant effects in research, suggesting potential applications well beyond antiviral support.
Important note: Shikimic acid is a precursor compound used in the manufacture of Tamiflu — it is not Tamiflu itself. We make no claims that sweet gum extract treats, cures, or prevents any disease. Always consult a qualified healthcare provider before using any herbal preparation.
Why the Green Balls Matter
Timing of harvest makes a significant difference in the potency of sweet gum preparations. The green, immature seed pods — collected before they dry, brown, and fall — contain the highest concentration of shikimic acid and active compounds. Research confirms that young seeds have a higher concentration of shikimic acid than older seeds, seed hulls, stems, or bark. Once the balls dry out and hit the ground, much of that medicinal value is diminished. This is why we harvest in season, by hand, while the balls are still green.
How We Harvest at Mayim Farm
Greg and Carole Lolley have farmed this land in Alabama since 2011. Sweet gum trees grow wild across our property and our neighbors’ land throughout the area — trees that have never been sprayed, fertilized, or chemically treated in any way. We wild harvest the green seed pods by hand each season, then tincture them slowly in alcohol to extract the full spectrum of beneficial compounds the tree has to offer.
What starts as the most despised tree in the Southern yard becomes, in our hands, one of the most interesting and valuable plants we work with. That transformation — from nuisance to medicine — is exactly the kind of story we love to tell at Mayim Farm.
