The Herb Anise
(Pimpinella anisum)
Koehler's Medicinal-Plants - 1887

The ripe seeds of anise contain about 2.5% of fragrant oil that is responsible for most of the beneficial effect associated with them. The oil consists mostly of antheole and its derivatives, like diantheole and photoantheole. Methylchavicol and para-methoxyphenylacetone, flavonoids like quercetin, and cumarins are also present.
Anise oil which is produced from crushed anise seed by steam distillation is valuable in perfumes and soaps, and has also been used in toothpastes, mouthwashes and skin creams.
When taken internally the anise seeds have been used to relief indigestion, colic, gas, halitosis, bloating, abdominal cramps and to remove nausea. The seeds have mild diuretic (increase urine output) and diaphoretic (increase sweating) properties and they have also been used for their antiseptic effects.
Anise oil works as an expectorant, which means it helps in the coughing up of mucus in conditions like asthma, bronchitis, the common cold, and the whooping cough. It is therefore being used as an ingredient in cough syrups and lozenges.
Anis seeds also have mild oestrogenic effects most likely due to the presence of diantheole and photoantheole in the oil. This is why the seeds have been used traditionally to promote lactation in nursing mothers, increase libido and to relief symptoms of premenstrual syndrome.
Ointments and soap containing anise oil can help as a natural remedy for oily skin and to treat impurities like mild acne.
Since anise oil is poisonous for many insects, ointments containing anise oil has also be used as a natural treatment for scabies and lice infestations.

Potential Side Effects of Anise

Anise oil is not without side effects, as large quantities used internally can cause nausea and vomiting, seizures and even pulmonary edema. This is why pure anise oil should not be used internally as pulmonary edema has occurred after ingestion of such a small quantity as 1-5ml pure anise oil. Using seeds internally is safe as they do not contain more than 2.5% oil. Used externally, pure anise oil can cause skin irritations, therefore the oil is formulated with other emollients to form an ointment in which the oil is sufficiently diluted to be safe. As with all natural products allergies can also develop which can potentially be life-threatening. Skin rashes, swelling of skin or tongue, difficulty breathing, and/or tightness in the chest could indicate a alergic reaction in which case a doctor should be consulted immediately. Anise should not be used during pregnancy and a health care provider should be consulted before the use by nursing mothers.
