Potential Uses of Flaxseed Oil for Overall Health: 

Potential uses of flaxseed oil for cancer 

Flaxseed oil contains alpha-linolenic acid (ALA), which may control breast cancer growth. It may help to lower the estrogen receptor, which might help stop the growth of cancer cells in the breast. Flaxseed also contains lignans which show antioxidant properties. Due to their estrogen-like activity, lignans resemble the effects of the hormone estrogen. These are helpful in estrogen metabolism, which is related to ovarian cancer and improved health. It may also be helpful in colon and skin cancer.1,2 As cancer is a severe condition, kindly consult the doctor for proper treatment. Do not self-medicate.  

Potential uses of flaxseed oil for wound healing 

Generally, a deficiency of essential fatty acids results in poor wound healing. Flaxseed oil is a rich source of essential fatty acids with linoleic acid (omega-6) and α-linolenic acid (omega-3). These components may regulate prostaglandin synthesis, which may fasten wound healing.1 Even so, kindly consult a doctor for diagnosis and treatment, and do not self-medicate as it may cause pain. 

Potential uses of flaxseed oil for hair 

The anti-inflammatory activity and omega-3 fatty acids in flaxseed oil may help hair growth. It may moisturise the damaged hair after application. It may also help increase the volume of hair. In addition, it may help soothe the scalp.4 However, more research is needed on the benefits of flaxseed oil for hair. Kindly consult a professional for better results. 

Potential uses of flaxseed oil for skin 

Flaxseed oil contains polyunsaturated fatty acids, linolenic acids, gamma-linolenic acid, and alpha-linolenic acid. These molecules are an essential part of our skin but are usually deficient in our diet. A healthy intake of flaxseed oil with a proper consultation from a nutritionist may help you fix these deficiencies.  It may be appropriate for all skin types, including oily, dry and normal.  Psoriasis and sunburns may also recover faster with flaxseed oil. 2,4 Even so, you must consult the doctor before using flaxseed oil instead of relying on flaxseed oil for solving your skin problems, as it may cause side effects. 

Potential uses of flaxseed oil for cholesterol 

Alpha-linolenic acid present in the flaxseed oil may help reduce triglycerides. It may also lower the very low-density lipoproteins (VLDL) or bad cholesterol in the liver. However, more research is needed to demonstrate the effects of flaxseed oil on human cholesterol levels.2 So, please consult the doctor for diagnosis and treatment. Do not self-medicate. 

Potential uses of flaxseed oil for cardiovascular health 

Flaxseed oil contains ALA, which may lower the risk of heart disease through various biological pathways. For example, it may help regulate platelet function, blood vessel health, inflammation, and arrhythmia (irregular heartbeat). In addition, a study conducted at Boston’s Simmons College shows that flax seed oil protects against heart attacks and circulation issues.2 Kindly consult the doctor for diagnosis and treatment. Do not attempt to self-medicate since conditions could worsen.  

Potential uses of flaxseed oil for haemorrhoids and constipation 

Haemorrhoids are a condition characterized by swollen and inflammatory veins located around the anus or in the lower part of the body. Flaxseed oil may facilitate stool passage in the intestines due to its fibrous structure. It may also be beneficial for constipation.2 However, more research is needed to check the effects of flaxseed oil on constipation and haemorrhoids. Kindly consult the doctor for an accurate diagnosis and treatment. 

Potential uses of flaxseed oil for gout 

Gout is a form of arthritis with symptoms such as pain, redness, tenderness and swelling in one or more joints, especially in one or both of the big toes. Alpha-linolenic acid in flaxseed may help reduce inflammation in the joints. It may also reduce the cholesterol level raised by gout. Flaxseed oil in gout may reduce swelling and joint pain.2 However, more research is required to study the effects of flaxseed oil on gout. Do not self-medicate, as it may cause serious adverse effects. Kindly consult the doctor for better health results. 

Though there are studies that show the benefits of flaxseed oil in various conditions, but these are insufficient and there is a need of further studies to establish the true extent of the benefits of flaxseed oil on human health.
