Oklahoma 8th-grader finds 56% of wild plants show antibacterial activity

In short

Locklyn Raye Ward began her project following a conversation with her father regarding the properties of wild pokeweed. To test their efficacy, she boiled one-gram botanical samples in distilled water to generate extracts for disc diffusion assays on cultured agar plates. The research evaluated these samples against both Escherichia coli and Staphylococcus epidermidis alongside commercial antibiotic controls. While seven native species proved capable of killing bacteria, traditional pharmaceutical antibiotics produced superior bacterial death across all trials.

Locklyn Raye Ward, an Oklahoma eighth-grader, worked on a study titled, “A Study of Open Field Plants, Native and Non-Native, and Their Antimicrobial Properties Against Escherichia coli and Staphylococcus epidermidis.” Details about Locklyn’s project and background come from the

Society for Science, the nonprofit behind Science News and several student science competitions. It all started with what she thought were weeds. One evening, Locklyn was feeding cows on the farm when she and her dad drove past some plants she thought were weeds. He told her it was pokeweed, growing wild. “He said he had always heard it was healthy in many ways,” she says. She was already worried about the overuse of antibiotics. So she started to wonder if other wild plants on the farm might have antibiotic properties and how those would compare with the antibiotics used in medicine. Locklyn picked 24 plants, and 12 of them were native to Oklahoma. She weighed each plant, cut it into one-gram pieces, and boiled it in distilled water to pull out any chemicals inside.

Next, she grew Escherichia coli and…
