Seed Purification or Detoxification (SHODHANA)

Ayurveda recommends detoxifying or purifying (SHODHANA) the seeds of Croton Tiglium (Jamalgota) before using it therapeutic purposes. The main target of this process is to reduce its irritant property. Jamalgota purification process includes following steps.

  1. Soak croton seeds overnight.
  2. Remove the outer coating (layer) of croton seeds.
  3. Remove leaf like cotyledons from inside the croton kernels.
  4. Tie in a cotton cloth and form bag (POTTALI) for steaming (SVEDANA) kernels.
  5. Now, add cow’s milk in stainless steel container (or ayurvedic instrument DOLA YANTRA) and heat it to boil and to produce steam.
  6. Now, hang the cotton bag with croton seeds above the milk container and immerse the bag in milk container. Give heat produced in the milk container for 3 hours.
  7. After that, remove seeds from cotton cloth and wash them with warm water.
  8. To reduce more irritant effect of croton kernels, then you should also press the kernels between two blotting papers to remove residual croton oil.
  9. Then dry then in the sun. Then the croton kernels can be stored in dry glass jar or earthen jar.
  10. To reduce side effects of kernels, limejuice is helpful. Ayurveda texts recommend processing (BHAVANA) croton kernels with limejuice three times.

However, this process reduces irritant effect and side effects of croton kernels and makes them suitable for human consumption, but croton kernels still have potent laxative action.

Benefits & Medicinal Uses

All parts of Croton Tiglium (Jamalgota) have strong purgative action. Therefore, the general benefit of Jamalgota is to eliminate the constipation.


Purified (SHODHIT) Croton Kernels: The purified (SHODHIT) croton (Jamalgota) kernels are used in ayurveda for constipation. The following mixture is beneficial and recommended in ayurvedic ancient texts to reduce side effects of croton kernels.

Croton Kernels Powder8 Parts (20 mg)
Borax Powder (Tankan Bhasma)1 Part (2.5 mg)

Ayurvedic physicians rarely use croton kernels alone. They have several ayurvedic formulations containing croton kernel (Jamalgota) powder.

Purified Jamalgota formulations are more beneficial for people with obstinate and persistent constipation if they have following symptoms or conditions.

  • They have not passed the stool since 3 days, but there is not bowel obstruction.
  • Indigestion or loss of appetite
  • AMA (Toxins developed due to undigested food)
  • Feeling heaviness in the abdomen, but no tenderness and abdominal pain

Croton Oil: Some folk physicians use 1 drop of croton oil mixing it with 1 tsp. honey or butter. Croton (Jamalgota) oil has very strong laxative and irritant action. Many people experience severe abdominal cramps, burning sensation in mouth, dizziness, vomiting and stupor. Therefore, we never believe it is UNSAFE for most people and we never recommend using croton oil internally for treating constipation. The purified (SHODHIT) croton kernels are safer option if patient urgently requires constipation management.

Croton Roots: Jamalgota or croton roots have mild laxative action, but roots may also cause mild burning in the abdomen like Jamalgota seeds.  However, croton roots are rarely used for laxative action, but roots increase the secretion of bile salts from the gall bladder and liver, which helps in removing constipation and treating jaundice.

Quick Point:

  • The oral use of unpurified seeds (croton kernels) and croton oil is likely unsafe. All these can cause severe inflammation in intestines and lead to intense abdominal pain and cramps.
  • Purified kernels may be useful for people with severe or chronic constipation, but the regular or frequent use of Jamalgota (purified kernels) is also unsafe. Its regular use may cause intestinal sluggishness and reduce natural peristalsis.


In hemorrhoids, croton roots are used externally in form of paste. The paste is made using the fine powder of croton roots and buttermilk. This paste is applied on external hemorrhoids. The external hemorrhoids shrink and become dry. The swelling is reduced and patient feels relief from all symptoms of hemorrhoids. This application is effective only for non-bleeding piles.

Contraindicating Symptoms & Conditions

The paste application of croton root should not be applied if patient has following symptoms.

  • Burning sensation
  • Fissure or Cuts
  • Bleeding piles
  • Fistula

Skin Tags (Acrochordon)

The paste of croton (Jamalgota) roots prepared with warm water is applied on the skin tags for several days. Skin tags naturally fall off after several regular applications.


The paste is prepared using water and external bark of croton roots. This paste is applied on the abscess. This paste helps bursting abscess. Some folks add turmeric (Curcuma Longa) powder in the paste for antiseptic purposes.


The external bark of croton roots is mixed with jaggery (Gur) and advised taking orally for increasing the bile secretion from the gall bladder and liver. This helps treating jaundice and reduces white stools.
