Karanja has rich and multiple healthy impacts; however, due to its salubriousity and side effects, it should be consumed moderately. Here are some essential precautions to consider:

• Allergic Reactions: The allergic reactions are some possible side effects of karanja oil or oil extract. However, if you intend to use this process on the skin, it is essential to perform a skin test, where you apply the substance on the forearm. Consult your doctor when you experience itching, redness, or inflammation, and stop using the product immediately.
• Pregnancy and Breastfeeding: Women who are pregnant or breastfeeding should not take karanja oil or any of the internal products derived from the karanja plant, as there is little research done on its use in these conditions.
• Internal Use: Although the leaves of the karanja tree are prescribed for treating digestive problems in traditional medicine, internal use of karanja oil can be fatal. You should only consider using Karanja-based products after consulting with an herbalist or a medical expert.
• Pre-existing Health Conditions: If you are a liver or kidney disease patient, then you have to avoid using karanja products as they will exacerbate your illness.

Karanja can have various applications for medicinal, agricultural, and skincare uses. Here are three standard methods:

1. Karanja Oil for Skin Care

Karanja oil has many healing properties and is predominantly used in treating skin disorders like eczema and psoriasis.

Steps to use:

• Wash the affected area with soap and warm water if personally involved; otherwise, avoid contact with the skin.
• Apply a few drops of Karanja oil to the skin and massage gently until absorbed. Use 1-2 times daily for best results.

2. Karanja Oil for Joint Pain

Sometimes, people suffer muscle or joint pain due to arthritis or injury. To eliminate the pain, they apply karanja oil as an effective painkiller.

Steps to use:

• Warm a small globule of the Karanja oil in your hands by rolling it between two palms.
• Then, gently circularly rub the oil on the skin in question for 5-10 minutes, letting the skin absorb the oil. Repeat daily or as needed.

3. Karanja Leaves for Stomach Disorders

Karanja is beneficial for digestion and can be used in indigestion as the plant leaves bear medicinal properties.

Steps to use:

• Crush a few tender fresh karanja leaves, add them in water, and boil them for 10-15 minutes.
• Filter the liquid, and the potion should be consumed once it has cooled. Take this product only once per day to alleviate signs of digestive distress.

The dosages of Karanja also differ depending on the form and for what. Just like all-natural remedies, it is essential to follow the right direction to eliminate the chances of side effects.

• Karanja Oil (Topical Use): For skin conditions such as eczema, apply 3-5 drops of karanja oil on the skin affected part 1-2 times a day for skin inflammation for psoriasis. Apply topically on the painful area for joint pain, and apply 5-10 drops twice daily.
• Karanja Leaf Decoction: To ease digestive ailments, it is suggested that five to seven fresh Karanja leaves should be boiled in water, the liquid filtered, and the patient should drink 100 to 150 ml of the decoction daily. Using it for an extended period is not recommended without first speaking to a doctor.
• Karanja Capsules or Supplements: If commercially available Karanja capsules are being used, then the dosage recommended on the packaging is usually 1-2 capsules daily.

Karanja interacts with different drugs, which may change the medicine’s efficacy or cause adverse effects. Here are some potential interactions to consider:

• Anticoagulants: Some studies have pointed out that Karanja has blood thinning properties and, as such, should not be taken along with anticoagulant drugs like warfarin since it will change the effects and create extra risk of blood loss. Healthcare provider supervision is required if you are under blood thinners.
• Diabetes Medications: Karanja may alter blood glucose levels, which could complement the action of diabetic medicines. The use of insulin can bring about hypoglycemia if properly checked by the body system. Most of the compounds in the use of insulin can lead to hypoglycemia when properly administered or inspected by the human body.
• Liver Metabolised Medications: Karanja may affect liver enzymes linked to the metabolism of drugs. Any drug metabolised primarily on the liver could become less effective or even more toxic if taken with Karanja.

Karanja, also known as Pongamia pinnata, has many health benefits. It can cure skin diseases, joint pains, and indigestion. The oil extracted from its seeds is also packed with anti-inflammatory and antimicrobial benefits. Therefore, it is widely used in folk remedies. Nevertheless, one must follow some precautions while taking Karanja as it can lead to allergic reactions, stomach upset issues, or may interfere with other medicines.
