If you've never heard of shikimic acid, you're not alone. It doesn't show up on supplement store shelves or wellness blogs the way turmeric and moringa do. But it's been quietly sitting at the center of some of the most important antiviral research of the last several decades — and it grows wild in the woods of southern Alabama.

Here's what shikimic acid is, where it comes from, and why people are increasingly looking for natural sources of it.

What Is Shikimic Acid?

Shikimic acid is a naturally occurring organic compound found in certain plants. It plays a central role in plant metabolism and has been studied extensively for its potential benefits in human health. For a more detailed overview, see our page on what shikimic acid is and how we source it.

Researchers have documented antiviral, anti-inflammatory, antioxidant, and antiplatelet properties in published studies. It's been investigated for its effects on respiratory viruses, blood clotting, and inflammation pathways. The interest in shikimic acid isn't fringe — it comes from mainstream pharmacological research going back decades.

Most people who've heard of shikimic acid know it from one context: it's the primary starting material used in the synthesis of a well-known antiviral medication. The pharmaceutical industry extracts it from star anise in enormous quantities for exactly this purpose. But shikimic acid itself is a plant compound, not a drug — and it exists in meaningful concentrations in several plants you may already be familiar with.

Natural Sources of Shikimic Acid

Shikimic acid is found in a range of plants, but concentrations vary enormously. The most significant natural sources include:

Sweet gum trees (Liquidambar styraciflua) — one of the richest known sources, particularly in the green seed pods Star anise (Illicium verum) — the primary commercial source used by the pharmaceutical industry Ginkgo biloba — contains shikimic acid in its leaves Wheatgrass and some conifers — lower concentrations

Of these, sweet gum trees are particularly interesting because they grow abundantly across the American South — and because their green seed pods contain some of the highest concentrations of shikimic acid found in any North American plant. We tell the full sweet gum tree story on its own page, covering history, botany, harvest, and what the research says.

Why Sweet Gum Trees Are a Uniquely American Source

Star anise — the primary commercial source of shikimic acid — is grown almost entirely in China and Vietnam. When global demand spikes, supply chains tighten and prices rise. Sweet gum trees are different. They're native to the eastern United States, grow wild across Alabama, Georgia, Mississippi, and the broader Southeast, and most landowners consider them a nuisance rather than a resource.

The key to harvesting sweet gum for shikimic acid is timing. The compound is most concentrated in the green seed pods — before they dry out and turn brown in fall. Green pods harvested at the right time contain significantly higher concentrations than dried pods, which is why timing and method matter as much as sourcing.

At Mayim Farm we hand harvest green sweet gum balls from our land and surrounding property in Opp, Alabama every season — picking at peak potency and processing in small batches to preserve the full spectrum of plant compounds.

What Does the Research Say?

Published research on shikimic acid has documented several areas of biological activity worth understanding:

Antiviral activity — shikimic acid has been studied for effects on respiratory and other viruses Anti-inflammatory properties — research has documented inhibition of inflammatory pathways Antioxidant protection — shikimic acid demonstrates free radical scavenging activity Antiplatelet effects — some studies suggest potential benefits for cardiovascular health

It's important to note that most research on shikimic acid has been conducted in laboratory settings or animal models. We're not making drug claims, and shikimic acid supplements are not a substitute for medical treatment. But the published science is substantial enough to explain why researchers and health-conscious individuals are paying attention to natural sources of this compound.

Whole Plant vs. Isolated Compounds

One thing worth understanding about plant medicine is the difference between isolated compounds and whole plant extracts. Pharmaceutical synthesis uses isolated shikimic acid as a starting material — extracting it, purifying it, and using it as a chemical building block.

Whole plant extracts like our Sweet Gum Ball Extract tincture work differently. Rather than isolating a single compound, the extraction process captures the full spectrum of the plant's natural chemistry — shikimic acid alongside terpenes, flavonoids, and other compounds that may work synergistically. This is the traditional herbalist approach, and it's why whole plant extracts have been used medicinally for thousands of years.

How to Get Natural Shikimic Acid

If you're interested in natural sources of shikimic acid, your options are more limited than you might expect. Star anise tea provides small amounts. A few supplement companies sell shikimic acid powder — usually derived from star anise through commercial extraction. And sweet gum ball tincture, made from hand harvested green pods, provides shikimic acid alongside the plant's full complement of natural compounds.

At Mayim Farm we produce both — a sweet gum ball extract tincture and a star anise extract — made in small batches on our farm in Opp, Alabama. We wild harvest our sweet gum balls from southern Alabama trees and process everything by hand with no additives, fillers, or preservatives.

Frequently Asked Questions

What is shikimic acid used for? Shikimic acid is a naturally occurring plant compound studied for antiviral, anti-inflammatory, antioxidant, and antiplatelet properties. It is also the primary starting material used in the pharmaceutical synthesis of certain antiviral medications. As a natural supplement, people use it as part of an immune support and general wellness routine.

What plants contain shikimic acid naturally? The highest concentrations of shikimic acid are found in sweet gum tree seed pods (Liquidambar styraciflua) and star anise (Illicium verum). It is also found in smaller amounts in ginkgo biloba, wheatgrass, and some conifers.

Is sweet gum tree a good source of shikimic acid? Yes — green sweet gum seed pods are one of the richest known natural sources of shikimic acid in North America. The key is harvesting them while still green, before they dry out. Sweet gum trees grow wild across the American South, making them one of the most locally abundant and sustainably harvestable sources of shikimic acid available.

How is shikimic acid extracted from plants? Commercial extraction typically uses chemical solvents and purification processes to isolate shikimic acid from star anise. Traditional herbal methods use alcohol extraction to produce a whole plant tincture that contains shikimic acid alongside other beneficial plant compounds. At Mayim Farm we use slow alcohol extraction to tincture green sweet gum balls harvested by hand in Opp, Alabama.

Can I get shikimic acid from star anise tea? Yes, star anise tea contains small amounts of shikimic acid. However concentrations in tea are lower than in concentrated tincture extracts. Star anise is one of the better dietary sources of shikimic acid and has been used in traditional medicine for centuries.

Is shikimic acid safe to take as a supplement? Shikimic acid from plant sources has a long history of use in traditional herbal medicine with a good safety profile. As with any supplement, consult your healthcare provider before use, especially if you are pregnant, nursing, or taking medications.

Where can I buy natural shikimic acid supplements? Natural shikimic acid supplements are available as sweet gum ball tinctures and star anise extracts. Mayim Farm produces both, wild harvested and small batch processed in Opp, Alabama. You can find our shikimic acid products at mayimfarm.com/collections/shikimic-acid.

The Bottom Line

Shikimic acid is a plant compound with a substantial body of research behind it and a unique position in both pharmaceutical science and traditional herbal medicine. Sweet gum trees — one of the most overlooked and underappreciated trees in the American South — are among the richest natural sources of it on the continent.

At Mayim Farm we've been harvesting them by hand in Opp, Alabama for years. What most people rake up and throw away, we turn into one of our most distinctive products — made by people who understand both the plant and the land it grows on.
