Bhargava Phytolab appears to specialize in homeopathic medicines and natural products.
Thunder M might be one of their products, although, without more context, it's hard to say exactly what it is. Homeopathic medicines typically use highly diluted substances to treat various ailments, and natural products often focus on using ingredients sourced from nature for health and wellness purposes. It's always a good idea to research any products thoroughly and consult with a healthcare professional before use, especially with alternative or complementary medicines like homeopathy.
