Of many Yogas formed by moon it is the most malefic yoga to have in a Kundali as per the classic texts. There is lots of opinion regarding the effects of Kemdruma Yoga lets us first see how Kemdruma Yoga is formed in a chart. If any planets are present before or/and after the moon i.e. in 2nd or 12th or in 2nd and 12th counted from the moon three yogas are formed namely Sunupha, Anapha, and Dhurdhara Yoga(Sun and both the nodes should not be considered) are formed, if there is none of the yogas present then it gives rise to Kemdruma Yoga.
It is said that one born under this Yoga even if born in a royal family will become unknown and will lead a miserable life. As per Varahamihira a native born under this yoga “even is of royal birth, will be dirty, sorrowful, doing work against his caste, poor, dependent and rougish”. So this yogas does not spare even a person born under a royal family. But the absence of any planet other than Sun and Nodes is not the only condition, to make a complete Kemdruma Yoga, there should not be any planets in the Kendra to Moon. Hence presence of planets in Kendra to Moon reduces the malefic effect of Kemdruma Yoga.
However, there are several conditions which lead to cancellation of Kemdruma Yoga, we cannot call it cancellation but it can reduce the bad effects to some extent:
1. If there are benefics in the Kendra to Moon or to the Lagna.
2. If Moon is associated with or aspected by benefics.
3. If Moon is in Own House or in his sign of Exaltation aspected by Jupiter.
4. If Full Moon occupy the Lagan.
5. The most important yoga which reduces the negativity of Kemdruma Yoga and blesses the native with very high position in society is presence of Kalpadruma Yoga.
"Note the following 4 grahas.
1. Lagnesh
2. The dispositor of Lagnesh
3. The dispositor of the graha at (2.) above.
4. The navamsa dispositor of the graha at (3.) above.
If all the 4 grahas defined above are disposed in angles and trines from the lagna, or be exalted, or own house only then Kalpadruma yoga exists. Anyone with this yoga will be endowed with all kinds of treasures and wealth, be a king , pious, strong, fond of war and be very merciful".
1. Lagnesh

These are some points which can reduce the effects of Kemdruma Yoga, but from all the above points its clear that association of planet with the Moon can reduce the effect of Kemdrum Yoga. But what is the logic behind it, we all know, Moon as considered as Queen in the horoscope hence a lone Moon signifies a lone Queen in the horoscope, and Moon being the significator of mind a lone Moon gives mental restless in respect of the house of which it is lord. It also makes native feel lonely and may lead to depression if its under malefic influence. Presence of Kemdruma Yoga does not always mean financial losess but mentel agony is sure.
We can find the presence of this Yoga in horoscope of many known person like Mahatama Gandhi in which the lone Moon is present with Rahu, but at the same time there were various Yogas to nullify the same like Moon in own house. Presence of Venus , Jupitrer and Mercury i.e. benefics in Kendra to Moon . And the most important presence of Kalpadruma Yoga, this yoga nullifies the effect of Kemdruma Yogas and elevates the native to a very high position.
Similarly, in Jennifer Aliston’s horoscope Moon is exalted with Jupiter aspecting it and the presence of Kalpadrum Yoga elevates her status in the society.
Ramalinga Raju has the same yoga in the horoscope with Moon in Aries , Jupiter , Venus and Exalted Saturn in Kendra but Kalpadrum Yoga is not present, further Moon is the lord of 9th house with signifies luck and suffered sudden downfall and his Moon is in 6th house which is the house of debt.
