Elderflower is readily known for childhood issues such as fever, upper respiratory infections and ear aches. It is known to help with spasmodic coughing and those with asthma, allergies or bronchitis. It also helps to get rid of phlegm. Elderflower has long been known to help support the immune system, as does the berries it produces later in the season. In turn it will help shorten the duration of a cold, and help lessen the symptoms. Elderflower may also help support blood flow. So those with any type of blood stagnation, elderflower may help. I foraged this plant in central Minnesota. Comes in a 1 oz bottle come with a dropper. Dosages - Tinctures are meant to be used as medicine in small amounts. Add 10-20 drops to your tea, juice, water or directly into your mouth when needed. Dosages for children are not provided in most herbals. To determine the correct dose you need to consider the size of the child, the ailment, the power of the herb you intend to use, and the adult dosage. Young's Rule for determining dosage uses the child's age divided by twelve plus the age. The dosage for a 4 year old: 4/12+4 = 4/16 = 1/4 of the adult dose. I use the folk method for making all my tinctures, which uses no measurements except sizing things up with your eyes. So I put the plant material in a jar and then fill with alcohol.
