For reciprocal reflexes (reciprocal constructions) you may use as a clarifyer mutuamente or one of the following:

(el) uno a(l) otro = (to) each other (two persons, male or one male and one female)

(la) una a la otra = (to) each other (two persons, both female)

(los) unos a (los) otros = (to) each other (more than two persons male or all male or male and female)

(las) unas a (las) otras = (to) each other (more than two persons, all female)

Note: The definite article is optional. The preposition a is used in these samples, but is often replaced by other prepositions depending on individual sentence.

Ella y yo nos queremos el uno al otro
She and I love each other.

Ellas se enojaron y se hicieron daño unas a otras.
