Hi there, I am sorry to hear about this problem. Recurrent colds can be problematic if your immune system is compromised in some way. Factors that can weaken the immune system include stress and lack of sleep so it is worth evaluating whether or not these are issues for you so that you can begin to deal with them.
Can I ask what type of Echinacea you have been taking? Generally speaking, fresh herb tincture is best absorbed by the body, though we also have our Echinacea Forte Tablets which deliver a high strength dose of the herb. It is best to take this as soon as you feel symptoms coming on, or if you have been in contact with anyone who has cold symptoms.
You may also want to think about other ways you can support the immune system. You may find the following blog has a few tips to help with this - How can diet boost our immune system?
Do you have questions? Please feel free to ask.
