Ketu is a powerful planet in Vedic astrology that can cause both positive and negative effects. To reduce the negative effects of Ketu, it is recommended to donate blankets, a calf, a goat, sesame, grey-colored materials and iron weapons. Additionally, fasting on Tuesdays and Saturdays can be helpful. Feeding a dog and Brahmins with rice cooked with cereals is also recommended. Being generous to the old and needy can also help to reduce the ill effects of Ketu. Praying to Lord Ganesha, who removes obstacles, can also be beneficial. Finally, it is believed that donating items such as bananas, jaggery and coconut to a temple will also reduce the ill effects of Ketu.
