My take on this is that I’ve been told that with any kind of autoimmune disease, you don’t take echinacea long-term. Some say that ANY echinacea is out.
Echinacea contains lectin that stimulates cytokine secretion by lymphocytes and their proliferation. That causes a general stimulation to the immune system and makes it more aggressive. Certainly for people with autoimmune diseases like Rheumatoid Arthritis, Lupus, Sjogrens etc, echinacea is out.
While it might be good for a cold or sore throat, it’s not good for the rest of the autoimmune process. In some people echinacea can exacerbate asthma too.
On the other hand, if your c-peptide is already whacked out, a couple of days on echinacea may not make that any worse.
Having said that, and while I’m not advising anyone to do this, when I get a sore throat that threatens to turn into a cold, I take a preparation (called Zinc Fix - available in Australia) that contains Vitamin C (1000mg) , zinc in various forms (100mg), magnesium in various forms (30mg), betacarotene (170mcg), and Vitamin B6 (5mg). It has worked a treat for years - no echinacea anywhere. I would only need to take this for a max of 2-3 days. Sometimes even one dose does the trick.
On the other hand, I recently told a friend about this supplement and it made him feel absolutely horrid. I scored a full bottle from him! I’m incredibly drug sensitive and this prep works great for me and sore throats turn into colds about once every 2 or 3 years. Yet I get them regularly, particularly when I’m around people who already have a cold.
Clearly something’s going on with you. Despite being a vegetarian, you could still be lacking something or the food balance may not be quite right for you at this time. Are you stressed? Does your multivitamin contain enough Vitamin C, or are you getting enough from food? I don’t know your age, but are you getting enough Vitamin D?
Maybe vary your diet eating less cooked food, or vary the food altogether, or include some vegetable juices (not fruit).You need a good juicer that doesn’t destroy enzymes - I do one with celery, tomato, spinach, raw garlic, a tiny bit of beetroot and a bit of salt and pepper. Always makes me feel great! It does need a little bolus though.
Oh yeah, and pamper yourself a little. It does wonders! A massage, a bath with your favourite oils… anything you like to make you feel less run-down!
I’m LADA too and have Lupus, another autoimmune disease, and I used to take echinacea for a couple of days with a sore throat until someone explained why I shouldn’t with Lupus. No idea if it’s the same with T1/LADA, but apparently GAD antibodies continue to be present in many T1s even after they’ve destroyed cells. Who knows what they’re still doing!
