• Cardiac glycosides: Relied on digitalis (foxglove) for the treatment of heart failures.
• Statins and antibiotics: Fungi and plants have also yielded cholesterol-lowering drugs and antibiotics essential to modern healthcare.

Natural products are particularly relevant for chronic and challenging conditions like cancer, infections, cardiovascular disease, and autoimmune disorders.

How Plant-Based Medicines Are Used

Herbal medicines can be consumed or applied in various forms:

• Teas and decoctions
• Capsules and tablets
• Essential oils and ointments
• Syrups and topical rubs

The efficacy and compound composition of each preparation can vary according to how it is processed, the plant source, extraction method, and even regional climate. This complexity is an area Dr. Lakshmikanthan continually seeks to standardize in his work.
