What is epithelial tissue and how does Ayurveda view it? - #16780

Recently, I was reading about different types of tissues in the human body and came across something called epithelial tissue. From what I understand, it’s a type of tissue that covers the skin, internal organs, and even the inside of the stomach and intestines. But what I don’t get is, is it just a protective layer, or does it have other functions too? And how does Ayurveda describe epithelial tissue? I’m curious because modern medicine explains it in a very mechanical way, but I feel like Ayurveda probably has a more holistic perspective on it. The reason I got interested in this is that I’ve been dealing with a lot of skin issues—eczema, recurring rashes, and general dryness that won’t go away no matter how much I moisturize. My digestion is also not the best, and I’ve heard that poor gut health can show up on the skin. Since the epithelial tissue is involved in both the skin and the digestive tract, I’m wondering if the two could be connected. Could it be that my epithelial tissue is weak or damaged? I’ve read that Ayurveda focuses a lot on Agni (digestive fire) and how imbalances in Agni can cause skin problems. If that’s true, does that mean my epithelial tissue is affected by my digestive health? Are there specific Ayurvedic treatments or herbs that can help strengthen epithelial tissue both externally (for my skin) and internally (for my digestion)? Also, are there particular foods that help with tissue regeneration in Ayurveda? I’ve been trying to eat cleaner, but I don’t know if I’m making the right choices. I would love to know if there are specific Ayurvedic remedies, dietary changes, or external applications that could help heal and strengthen my epithelial tissue naturally. Would really appreciate any insights from an Ayurvedic perspective!
