Chemical Compounds In Asafoetida Oil

Note: Asafoetida has high amounts of foetidine and 2-butyl ethyl trisulfide.

Asafoetida is a great source of carbohydrates, proteins, fat, minerals, but with a small amount of fiber. It consists of three main fractions: (2)

  • The resin (in a big amount)
  • The gum
  • The essential oil (in a small amount)

The resin contains ferulic acid, esters, and terpenoids such as coumarins, sesquiterpene coumarins, etc.

The gum consists of glucose, rhamnose, galactose, 1-arabinose, glucuronic acid, polysaccharides, and glycoproteins.

The volatile fraction has a rich amount of sulfur-containing compounds, monoterpenes, and terpenoids.

Three major sulfur constituents are:

  • 1-(methyl this) propyl 1-propenyl disulfide
  • 2-butyl 1-propenyl disulfide
  • 2-butyl 3-(methyl this)-2-propenyl disulfide.8

Asafoetida is a strong or potent herb, which is often used as a strong abortifacient. Consuming its oil (but diluted in warm water) orally helps in raising the temperature of the uterus.

When the temperature of the uterus rise, it triggers the breakdown of corpus luteum, causing abortion in the early stage of pregnancy.

The resin of asafoetida increases the amplitude and has been found decreasing the latent period of the action potential of nerve compounds. It works as a neuro-stimulant. The oil is also found effective for epileptic patients. It is found helpful in boosting the memory. (13)

6. Effective against cancer

Asafoetida is found to be a potent antioxidant herb. It has the capacity to reduce free radicals. As you know, free radicals are the root cause of cell damage and can trigger the carcinogenesis in the cells.

However, you can prevent free radicals by consuming foods that are rich in antioxidants. Happily, asafoetida is one amongst them. It is also found effective against carcinogenic chemicals like 7, 12 dimethyl benzanthracene and croton oil. It helps in reversing the induced ODC activity and DNA synthesis. (14, 15)

Side Effects Of Asafoetida Oil

Asafoetida is one of the commonly used spices in Indian dishes. It can be applied on the nails and stomach of infants who can’t take it orally to get rid of acidity. Since no definite dose is yet known, we strongly recommend not to use if you have:

  • Low blood pressure or hypotension
  • Bleeding disorders

If you take asafoetida despite having hypotension, it can show adverse effect with medicines such as enalapril (Vasotec), valsartan (Diovan), captopril (Capoten), losartan (Cozaar), Amlodipine (Norvasc), furosemide (Lasix), diltiazem (Cardizem), and hydrochlorothiazide (HydroDiuril).

It can also show severe effects in bleeding disorder if provided with drugs such as clopidogrel (Plavix), aspirin, diclofenac (Voltaren, Cataflam etc), naproxen (Anaprox, Naprosyn etc), heparin, dalteparin (Fragmin), and warfarin (Coumadin).

Asafoetida is considered as a safe drug and spice when taken orally. But it can be risky in early as well as later stages of pregnancy. Being hot in nature it can cause miscarriage in the first trimester and heavy bleeding even in later trimesters of the pregnancy.

People who are allergic for asafoetida have swelling of lips, burning sensation, diarrhea, gastric trouble, convulsion, bleeding disorders, and other adverse effects.

It must not be given to infant orally, as this can cause bleeding disorders. It can even increase the risk of bleeding in adults. For epileptic patients, if given in excess amounts, it can cause seizures.

Although asafoetida is good for the digestive system, it can cause infection in the GI (Gastrointestinal) tract. People suffering from hypotension must avoid the uses of asafoetida, as it can mismanage the blood pressure control.
