Don’t forget, our December sale is on! Details below.

It’s time we resumed our exploration of the top-selling herbs as supplements in the US! We're three-quarters of the way through the main list. (Remember we’re working with the 2023 data for the purposes of this series, but I gave some updates about the 2024 Herbal Market Report data in the last installment.)

Our herbs today are valerian, pumpkin (seed [oil]), goji berry, and red yeast rice. There are some fun details about each of these, including…

• how to predict if valerian will keep you awake instead of helping you sleep,
• why certain medicinal seed oils are promoted in a gender-based dichotomy,
• who should not take goji, and
• why everyone should probably avoid red yeast rice supplements.

Listen for the full story.
