A move that might totally change how we produce these medicinal molecules for research and medicine.Ashwagandha’s been a staple in Indian medicine for ages, mostly for easing stress and helping with sleep. The plant’s roots pack a punch because of withanolides, a group of natural steroid-like compounds. The old way—growing and harvesting the whole plant just for these chemicals—takes a ton of time and resources.

But now things are different. In a study in Nature Plants, Jing-Ke Weng and his team at Northeastern University engineered yeast by adding six genes that handle withanolide production. After just a few days, the yeast started pumping out the compounds. So, instead of waiting months for a harvest, you get what you need in less than a week.
Weng says their engineered yeast could be the first step toward making withanolides at an industrial scale. It’s a faster, less land-hungry way to get these molecules.
Why does this matter? Yeast grows fast and thrives in big tanks, which means this method could make withanolides much easier to get for both researchers and companies. That’s a big deal for supplement makers and drug developers who need a steady, reliable supply of these compounds.
Right now, ashwagandha supplements are everywhere, advertised for stress and sleep. But the science is still catching up. With more of these pure withanolides on hand, researchers can finally run better studies on what they actually do—whether for inflammation, brain health, or something else.

This breakthrough isn’t just about ashwagandha, either. It shows how synthetic biology can help us make rare plant compounds that are usually expensive or tricky to extract. With this kind of tech, scientists could design new versions of plant-based medicines with specific benefits.
There’s still work to do before this is ready for mass production, but it’s a huge leap toward blending ancient plant wisdom with modern biotech.
