Thank you for the question. A well prescribe homeopathic remedy is your most effective cure for an upper respiratory infection. In the absence of a homeopath to take your case I would suggest using a combination of herbs, vitamins and flushing the sinuses to clear your symptoms.
There are many over the counter herbal combination for immune boosting, seek advice at your local health food store for the best product.
Increasing your vitamin C, and zinc will support your immune response as well. I recommend flushing the sinuses either with warm salt water or very dilute colloidal silver (which you can also take internally) to reduce the surface organisms living in your sinuses. Drink lots of water and get plenty of rest.
The pink eye is a little more complicated and you may want to seek medical treatment for that issue.
Several herbs have been traditionally used to treat eye inflammation. Examples include calendula, eyebright, chamomile, and comfrey. Click here for an article on pink eye. In Health
