Keeda Jadi, also known as Cordyceps sinensis or caterpillar fungus (Ophiocordyceps sinensis), is a remarkable type of fungus that flourishes on certain caterpillar species, found in the high-altitude regions of India, China, and Nepal. This unique fungus has gained popularity due to its numerous health benefits. By stimulating specific cells and chemicals within the immune system, Cordyceps contributes to bolstering immunity. Moreover, it exhibits potential in fighting against cancer cells and has been observed to reduce tumor size, particularly in lung or skin cancer cases.
