Smell Your Way to Joy: The Science Behind How Plants and Aromatherapy Enhance Memory and Emotion

Growing Joy with Plants - Wellness Rooted in Nature, Houseplants, Gardening and Plant Care

Did you know the scent of plants can do more than just make your garden smell good? It can actually improve your mood, your memory, and your overall health. I’ve always thought of plant scents as just a lovely bonus in the garden, but I didn’t know there’s some wild science behind how smell connects to our emotions and even our brains. And to help me with that is Dr. Rachel Herz, a neuroscientist and expert on the psychology of scent. She explains how the smells from our plants can shape how we feel, what we remember, and how we heal.

In this episode, we learn:

• [03:06] How did Dr. Herz start her career in the science of scents?

• [21:43] What’s the role of the olfactory bulbs?
• [22:36] Why is the nose a significant entry point for substances entering the body?
• [25:12] Why do people often think smell is the least important sense?
• [27:25] Losing sight vs smell
• [30:20] Gardeners Supply Company’s
• [32:48] The perception of a smell as "good" or "bad"
