Grapefruit is a citrus fruit. People make medicine out of the fruit, the oil from the peel, and the extracts from the seeds. Grapefruit seeds and pulp that are left over from making grapefruit juice are used to make grapefruit seed extract. To make the final product less acidic and bitter, vegetable glycerin is added.
Grapefruit juice is used to treat asthma, high cholesterol, “hardening of the arteries” (atherosclerosis), cancer, low red blood cell counts, psoriasis, and to help people lose weight and get rid of obesity. It is also given to people with eczema to help them feel better in their stomachs (atopic dermatitis).
Grapefruit seed extract is taken by mouth to treat yeast infections and infections caused by bacteria, viruses, and fungi.
Grapefruit oil is used to treat sore muscles, grow hair, tighten the skin, get rid of acne, and treat oily skin. It is also used to treat the common cold, influenza, and swine flu.
Grapefruit seed extract is used to clean the face, treat minor skin irritations, and treat yeast infections in the vaginal area (candidiasis). It is also used as a rinse for the ears or nose to prevent and treat infections, as a gargle for sore throats, in a shampoo to get rid of lice, as a dental rinse to prevent gingivitis and promote healthy gums, and as a breath freshener.
Some people breathe in the vapours of grapefruit to help their bodies hold on to water, get rid of headaches, stress, or depression. People with lung infections have also breathed in the vapour of grapefruit seed extract.
Grapefruit is eaten as a fruit, made into juice, and used to add flavour to food and drinks.

It’s important to keep in mind that drug interactions with grapefruit juice have been studied and written about a lot. The chemistry of a grapefruit depends on what kind it is, how it grows, and how the juice is taken out. If you already take medicine, talk to your doctor before adding grapefruit to your diet or list of natural medicines.
How does it work?
Grapefruit has a lot of good things for you in it, like vitamin C, fibre, potassium, pectin, and more. Some parts may have anti-oxidant effects that could help prevent damage to cells or lower cholesterol.
It’s not clear how the oil could be used as a medicine.
SPECIAL PRECAUTIONS & WARNINGS
Pregnancy and breastfeeding: We don’t know enough about how grapefruit affects women who are pregnant or who are nursing. To be safe, you should not use.
Some people worry that drinking too much grapefruit juice could lead to breast cancer. Some studies have shown that postmenopausal women who drink a quart or more of grapefruit juice every day are 25% to 30% more likely to get breast cancer.
Grapefruit juice slows down how the body breaks down oestrogen, which could cause oestrogen levels to rise. We need to do more research to confirm these results. Don’t drink too much grapefruit juice until more is known, especially if you have breast cancer or are at a higher risk than usual of getting it.
Heart muscle diseases: if you drink grapefruit juice, you might be more likely to have an abnormal heart rhythm. Grapefruit juice should be used in moderation by people with these diseases.
Hormone-sensitive cancers and diseases: If you eat a lot of grapefruit, your hormone levels might go up, which could increase your risk of hormone-sensitive diseases. Women with conditions that are sensitive to hormones should stay away from grapefruit.
The right amount of grapefruit to take depends on the person’s age, health, and a number of other things. At the moment, there isn’t enough scientific information to know what doses of grapefruit are right.
Remember that natural products aren’t always safe, and that doses can be important. Make sure to follow the directions on the labels and talk to your pharmacist, doctor, or other medical professional before using.
