-- The Intersection of Machine Learning and Herbal Medicine -- Herbal medicines (HMs) have long been associated with holistic healing, sleep enhancement, and inflammation reduction. Claims that aloe vera hydrates better than water or that certain herbal teas induce sleep are widely popular—but how do we separate scientific fact from myth? With advancements in machine learning (ML) and Convolutional Neural Networks (and respective Deep Neural Networks such as MLPs, RNNs, etc.) and mass spectrometry imaging (MSI), we can now analyze herbal medicines at a molecular level, mapping their active compounds and pharmacological effects. In this blog (don't worry, we are not here to make you feel guilty for drinking coffee), we’ll explore how modern technology is revolutionizing herbal medicine, examining how scientific methods like MSI, SIMS, MALDI, and DESI are used to validate traditional remedies. Herbal medicine has been practiced for centuries, often supported by anecdotal evidence; however, elucidating the mechanisms underlying its efficacy remains challenging. Unlike synthetic pharmaceuticals, in which active ingredients are isolated and systematically analyzed, herbal medicines consist of complex mixtures of bioactive compounds that may exhibit synergistic effects or potential interactions. MSI allows scientists to map the chemical composition of herbal medicines without destroying their structure, offering insights into the spatial distribution of bioactive metabolites (Zhang et al., 2024). For example, if a herbal tea is claimed to help with sleep, we can reveal whether its compounds interact with neurotransmitters like GABA or serotonin, which regulate sleep cycles and hormone efficacy. These MSI techniques use different ionization methods to analyze herbal compounds. ⛔ Hold on now, do not put away your Melatonin pills just yet 💊.
